Why GTA 4 does not enter the game. problem solving. Errors when the game does not start

Description

quite common on Windows 7/8/10. Most often, this error prevents you from playing due to inappropriate or missing Windows software, namely Microsoft Visual C ++.

Solving the problem with the SecuLauncher error

How to fix the error SecuLauncher: failed to start application.? Very simple! Solve the problem of You can install the correct version of Microsoft Visual C++. And so, for this you need:

1. Download Microsoft Visual C++ 2005 SP1 Redistributable Package (x86) from official site . Link to download the official software below:

2. Uninstall previous version of Visual C++

3. Install the previously downloaded Visual C++ 2005

4. Enjoy the game

You can also download the Visual Collection 2005-2017 if you have any difficulties with the installation from the link above. To install, simply run the downloaded file.

Grand Theft Auto 4 won't install

If Grand Theft Auto 4 does not install, check if there is enough free space on your hard drive. The distribution requires free space, so a few gigabytes of extra space won't hurt. Many modern games require a significant volume.

Installing Grand Theft Auto 4 is blocked by antivirus

Often, antivirus programs, in the fight against viruses, protecting our computer from external threats, for security purposes, block numerous processes performed by the operating system. Sometimes such security is so strong that the antivirus blocks access not only to viruses, but also suspends some normal processes, perhaps by mistake, considering them potentially vulnerable. Disable your antivirus during installation.

Cleaning the computer and restarting

Sometimes, a simple reboot of the system can immediately solve many problems that arise both during the installation of games and their subsequent work. The same applies to programs and applications. There are many reasons: the computer is clogged with garbage, the system cache is full, the maximum allowable number of simultaneously running processes, some may be frozen and not running, but they put a load on the system. Cleaning the computer and restarting will fix the situation.

No Internet access

Some game clients during the installation process require an Internet connection, providing access to the installation server or update server. Make sure the connection is good, and if there is no Internet, be prepared for problems when installing Grand Theft Auto 4. It's good if the system displays an error message. And if there is none, you can think for a long time and wonder why the toy is not installed.

Grand Theft Auto 4 won't start

Before looking for reasons why Grand Theft Auto 4 won't start, make sure the installation itself was successful. Otherwise, if there were failures during the installation process, but at the same time the game was installed, it is impossible to guarantee the subsequent launch and performance. If it starts - lucky. What will happen next is unknown. Remember the installation process.

Reinstalling the game

Many gamers have repeatedly encountered a situation where they had to reinstall games. Apparently, this is the case where reinstalling Grand Theft Auto 4 will fix the problem. It is not known what this is connected with, maybe the antivirus or firewall "ate" some files or something else at the time of installation, but after installing the game again, it starts up and works. Uninstall Grand Theft Auto 4 and reinstall, paying attention to every detail during this process. Perhaps at some point the program will ask for additional files, etc.

There are times when installing on top of an already installed game solves the situation. The installer may offer to update the files. Thus, there is no need for removal. Well, something like this.

Finding information by error text

Another option. Problems when starting Grand Theft Auto 4 are usually accompanied by a corresponding system message. Specify the text of the error in the search, as a result of which you will receive the most detailed answer, and, moreover, regarding this particular problem. Actually, the decision will not keep you waiting. This way you can pinpoint the cause and fix the problem.

By the way, for some reason I always forget about it. Until I turn over the whole computer. But this the method works for all 92%. It is enough just to score the text in the search and find a useful article. So you will definitely solve the problem, you do not need to send the PC to the workshop ahead of time and incur additional costs. There is a lot of useful material on the Internet - study it.

Running Grand Theft Auto 4 as administrator

Run the game as an administrator. In our case, to run Grand Theft Auto 4 as an administrator, you need to right-click on the game's shortcut and select Run as administrator. Subsequently, if this method solves the problem, make it the default. Open the Shortcut Properties, in the Compatibility tab, and check the box Run this program as an administrator.

Grand Theft Auto 4 is not compatible with the system

Another obstacle to running Grand Theft Auto 4 may be incompatibility with your operating system. In this case, all in the same place, in the Properties of the shortcut, add the checkbox Run the program in compatibility mode, select the desired OS from the drop-down list.

.NET Framework not installed

A very serious problem with running Grand Theft Auto 4 is the lack of an installed .NET Framework library on the computer, which ensures the launch and maintains the performance of programs and applications, including games. This is a prerequisite and Microsoft .NET Framework must be installed on your PC.

There are different versions of the .NET Framework. The presence of any one of them on the computer cannot sufficiently guarantee the correct operation of the program. If, for example, the library is already installed on the computer, but the game requires it, download and install it. Restart your PC. The previous version will not be deleted or overwritten. They will just work together.

Use programs that will prepare your computer for the correct operation of the game, help to avoid many problems and errors.

Availability of DirectX

Perhaps the most important condition, a requirement that must be met for games, including Grand Theft Auto 4, is the presence of an installed . No toy will work without it. Almost all distributions that require DirectX installed already have this set in their composition.

As a rule, DirectX is installed automatically during installation. If it is not in the distribution, download and install. It is not necessary to do this before installation, it is possible after, but the presence on the computer is simply necessary. Download links are located above.

What to do if Grand Theft Auto 4 is not working?

Do not despair if you have already gone through all the ways and nothing helps, the game does not work. Perhaps these tips will seem too vague, incomprehensible, errors are still present. Check again, did you do everything right? If necessary, download another distribution of Grand Theft Auto 4, if purchased in a store, contact the seller (manufacturer) for help. Maybe the disk is corrupted, something is missing. It's normal, quite natural, it happens. Use a different distribution and install the game again.

As a last resort, there are situations when the operating system is still incompatible with Grand Theft Auto 4. Update the system using Windows tools (via Update Center). The game will work. If the manufacturer indicated compatibility, then he is responsible for this. Update your operating system.

Reinstalling the OS is a last resort. Not sure about statements like "the operating system is pirated... assembly... won't work..." or "a hacked, pirated toy - throw it away ...". The moment that is worth your attention is to remember if there were similar problems with other games, in particular those similar to Grand Theft Auto 4. And if problems were observed, this suggests that it may be time to update something in the system or reinstall . Thank you for attention!

Other materials

Unfortunately, there are flaws in games: brakes, low FPS, crashes, freezes, bugs and other minor and not very errors. Often problems begin before the game even starts, when it won't install, won't load, or won't even download. Yes, and the computer itself is sometimes weird, and then in GTA 4, instead of a picture, a black screen, control does not work, no sound is heard or anything else.

What to do first

Download and run the world famous CCleaner(download from a direct link) is a program that will clean your computer of unnecessary garbage, as a result of which the system will work faster after the first reboot;
Update all drivers in the system using the program Driver Updater(download via direct link) - it will scan your computer and update all drivers to the latest version in 5 minutes;
Install Advanced System Optimizer(download from a direct link) and turn on the game mode in it, which will end useless background processes during game launch and improve performance in the game.

The second thing to do if you have any problems with GTA 4 is to check the system requirements. In a good way, you need to do this even before the purchase, so as not to regret the money spent.

Minimum system requirements for Grand Theft Auto 4:

Windows XP, Intel Core 2 DUO, 1.5 Gb RAM, 16 Gb HDD, nVidia GeForce 7900 256 Mb

Every gamer should at least have a little understanding of the components, to know why a video card, processor and other things are needed in the system unit.

Files, drivers and libraries

Almost every device in a computer requires a set of special software. These are drivers, libraries and other files that ensure the correct operation of the computer.

It's worth starting with the drivers for the video card. Modern graphics cards are produced by only two large companies - Nvidia and AMD. Having found out which product spins the coolers in the system unit, we go to the official website and download the package of fresh drivers:

A prerequisite for the successful functioning of Grand Theft Auto 4 is the availability of the latest drivers for all devices in the system. Download the utility Driver Updater to easily and quickly download the latest drivers and install them with one click:

If Grand Theft Auto 4 does not start, we recommend that you try disabling your antivirus or put the game in the antivirus exceptions, and also check the system requirements again and if something from your build does not match, then, if possible, improve your PC by purchasing more powerful components.

In GTA 4 black screen, white screen, color screen. Solution

Problems with screens of different colors can be roughly divided into 2 categories.

Firstly, they are often associated with the use of two video cards at once. For example, if your motherboard has a built-in video card, but you play on a discrete one, then Grand Theft Auto 4 may run on the built-in one for the first time, while you will not see the game itself, because the monitor is connected to a discrete video card.

Secondly, color screens happen when there are problems with displaying the image on the screen. This can happen for various reasons. For example, Grand Theft Auto 4 cannot run through an outdated driver or does not support a video card. Also, a black / white screen may be displayed when working at resolutions that are not supported by the game.

Grand Theft Auto 4 is crashing. At a certain or random moment. Solution

You play for yourself, play and here - bam! - everything goes out, and now you have a desktop without any hint of the game. Why is this happening? To solve the problem, it is worth trying to figure out what the nature of the problem is.

If the crash occurs at a random point in time without any pattern, then with a probability of 99% we can say that this is a mistake of the game itself. In this case, fixing something is very difficult, and the best thing to do is to just put Grand Theft Auto 4 aside and wait for the patch.

However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash.

However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash. In addition, you can download the Grand Theft Auto 4 save and bypass the departure point.

Grand Theft Auto 4 freezes. The picture freezes. Solution

The situation is about the same as with crashes: many freezes are directly related to the game itself, or rather, to the developer's mistake when creating it. However, a frozen picture can often become a starting point for investigating the deplorable state of a video card or processor.

So if the picture in Grand Theft Auto 4 freezes, then use the programs to display statistics on the loading of components. Perhaps your video card has long exhausted its working life or the processor is heating up to dangerous temperatures?

The easiest way to check the loading and temperatures for the video card and processors is in the MSI Afterburner program. If desired, you can even display these and many other parameters on top of the Grand Theft Auto 4 picture.

What temperatures are dangerous? Processors and video cards have different operating temperatures. For video cards, they are usually 60-80 degrees Celsius. The processors are slightly lower - 40-70 degrees. If the processor temperature is higher, then you should check the condition of the thermal paste. It may have dried out and needs to be replaced.

If the video card is heating up, then you should use the driver or the official utility from the manufacturer. You need to increase the number of revolutions of the coolers and see if the operating temperature drops.

Grand Theft Auto 4 is slow. Low FPS. Frame rate drops. Solution

With brakes and low frame rates in GTA 4, the first step is to lower the graphics settings. Of course, there are a lot of them, so before reducing everything in a row, you should find out exactly how certain settings affect performance.

Screen resolution. In short, this is the number of points that make up the picture of the game. The higher the resolution, the higher the load on the video card. However, the increase in load is negligible, so reducing the screen resolution should only be the last resort, when everything else does not help.

Texture quality. Typically, this setting determines the resolution of texture files. Decrease the quality of textures if the video card has a small amount of video memory (less than 4 GB) or if you are using a very old hard drive with a spindle speed of less than 7200.

Model quality(sometimes just details). This setting determines which set of 3D models will be used in the game. The higher the quality, the more polygons. Accordingly, high-poly models require more processing power of the video card (not to be confused with the amount of video memory!), which means that this parameter should be reduced on video cards with a low core or memory frequency.

Shadows. They are implemented in different ways. In some games, shadows are created dynamically, that is, they are calculated in real time every second of the game. Such dynamic shadows load both the processor and the video card. In order to optimize, developers often abandon the full rendering and add a pre-render of shadows to the game. They are static, because in fact they are just textures that are superimposed on top of the main textures, which means they load memory, and not the core of the video card.

Often, developers add additional settings related to shadows:

Shadow Resolution - determines how detailed the shadow cast by the object will be. If the game has dynamic shadows, then it loads the core of the video card, and if a pre-created render is used, then it “eats” the video memory.
Soft shadows - smoothing out bumps on the shadows themselves, usually this option is given along with dynamic shadows. Regardless of the type of shadows, it loads the video card in real time.

Smoothing. It allows you to get rid of ugly corners at the edges of objects by using a special algorithm, the essence of which is usually to generate several images at once and compare them, calculating the most “smooth” image. There are many different anti-aliasing algorithms that differ in the level of impact on GTA 4 performance.

For example, MSAA works head-on, creating 2, 4, or 8 renders at once, so the frame rate is reduced by 2, 4, or 8 times, respectively. Algorithms such as FXAA and TAA operate a little differently, achieving a smooth image by calculating only the edges and using some other tricks. Because of this, they do not reduce performance as much.

Lighting. As in the case of anti-aliasing, there are different algorithms for lighting effects: SSAO, HBAO, HDAO. All of them use the resources of the video card, but they do it differently depending on the video card itself. The fact is that the HBAO algorithm was promoted mainly on video cards from Nvidia (GeForce line), so it works best on the “green” ones. HDAO, on the other hand, is optimized for AMD graphics cards. SSAO is the simplest type of lighting, it consumes the least resources, so in case of brakes in Grand Theft Auto 4, it is worth switching to it.

What should be lowered first? Shadows, anti-aliasing, and lighting effects are usually the most stressful, so it's best to start with them.

Often, gamers themselves have to optimize GTA 4. For almost all major releases, there are various relevant forums where users share their ways to improve performance.

One of them is a special program called Advanced System Optimizer. It is made specifically for those who do not want to manually clean up the computer from various temporary files, delete unnecessary registry entries and edit the startup list. Advanced System Optimizer will do this on its own and will also analyze your computer to find out how you can improve performance in applications and games.

GTA 4 is lagging. Big game delay. Solution

Many people confuse "lag" with "lag", but these problems have completely different causes. Grand Theft Auto 4 slows down when the frame rate at which the image is displayed on the monitor decreases, and lags when the delay when accessing the server or any other host is too high.

That is why "lags" can only be in network games. The reasons are different: bad network code, physical distance from servers, network congestion, incorrectly configured router, low Internet connection speed.

However, the latter is the least common. In online games, communication between the client and the server occurs by exchanging relatively short messages, so even 10 MB per second should be enough for the eyes.

There is no sound in Grand Theft Auto 4. Can not hear anything. Solution

GTA 4 works, but for some reason does not sound - this is another problem that gamers face. Of course, you can play like that, but it's still better to figure out what's the matter.

First you need to determine the scope of the problem. Where exactly is there no sound - only in the game or in general on the computer? If only in the game, then perhaps this is due to the fact that the sound card is very old and does not support DirectX.

If there is no sound at all, then the matter is definitely in the computer settings. Perhaps the sound card drivers are not installed correctly, or maybe there is no sound due to some specific error of our favorite Windows OS.

Controls not working in Grand Theft Auto 4. Grand Theft Auto 4 does not see the mouse, keyboard or gamepad. Solution

How to play if it is impossible to control the process? The problems of supporting specific devices are out of place here, because we are talking about familiar devices - keyboard, mouse and controller.

Thus, errors in the game itself are practically excluded, almost always the problem is on the user's side. You can solve it in different ways, but, one way or another, you will have to turn to the driver. Usually, when you connect a new device, the operating system immediately tries to use one of the standard drivers, but some models of keyboards, mice, and gamepads are not compatible with them.

Thus, you need to find out the exact model of the device and try to find exactly its driver. Often, devices from well-known gaming brands come with their own software kits, since the standard Windows driver simply cannot ensure the correct operation of all the functions of a particular device.

If you don’t want to look for drivers for all devices separately, you can use the program Driver Updater. It is designed to automatically search for drivers, so you only need to wait for the scan results and download the necessary drivers in the program interface.

Often, the brakes in GTA 4 can be caused by viruses. In this case, there is no difference how powerful the video card is in the system unit. You can check your computer and clean it of viruses and other unwanted software using special programs. For example NOD32 . The antivirus has proven itself from the best side and has received the approval of millions of users around the world.

Suitable for both personal use and small businesses, ZoneAlarm is able to protect a computer running Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP from any attack: phishing, viruses, malware, spyware and other cyber threats . New users are given a 30-day free trial.

Nod32 is an antivirus from ESET, which has received many awards for its contribution to the development of security. Versions of anti-virus programs for both PC and mobile devices are available on the developer's website, a 30-day trial version is provided. There are special conditions for business.

Grand Theft Auto 4 torrent download not working. Solution

If the distribution kit of the game was downloaded via torrent, then in principle there can be no guarantees of work. Torrents and repacks are almost never updated through official applications and do not work over the network, because in the course of hacking, hackers cut out all network functions from games, which are often used to check the license.

Using such versions of games is not only inconvenient, but even dangerous, because very often many files have been changed in them. For example, to bypass protection, pirates modify an EXE file. However, no one knows what else they do with it. Maybe they embed self-executing software. For example, which, when the game is first launched, will be integrated into the system and will use its resources to ensure the well-being of hackers. Or, giving access to the computer to third parties. There are no guarantees and there cannot be.

In addition, the use of pirated versions is, according to our publication, theft. The developers have spent a lot of time creating the game, investing their own money in the hope that their offspring will pay off. And every work must be paid.

Therefore, if you encounter any problems with games downloaded from torrents or hacked using certain means, you should immediately remove the “pirate”, clean your computer with an antivirus and a licensed copy of the game. This will not only save you from dubious software, but also allow you to download updates for the game and receive official support from its creators.

GTA 4 gives an error about the absence of a DLL file. Solution

As a rule, problems associated with the absence of DLLs occur when Grand Theft Auto 4 is launched, however, sometimes the game can access certain DLLs in the process and, without finding them, crash in the most impudent manner.

To fix this error, you need to find the required DLL and install it on the system. The easiest way to do this is with a program. DLL fixer, which scans the system and helps you quickly find missing libraries.

Thank you for your attention!

One of the most popular games today is GTA 4, which has won the love of a huge number of gamers around the world. Players love this game because it allows you to do whatever your heart desires in a virtual city, and also has an interesting story. However, there may be difficulties when launching GTA 4. Few gamers understand how to run GTA 4 if it does not run correctly on the computer.

Consider possible problems and their solutions.

GTA 4 system requirements

If the GTA 4 game does not start, then your computer may not meet the minimum system requirements:

Processor: Intel Core 2 Duo 1.8 GHz, AMD Athlon 64 X2 2.4 GHz;
RAM: 1.5 GB (Windows XP) 2 GB (Windows Vista);
Video card: 256 MB Nvidia GeForce 7900 / 256 MB ATI Radeon x1900;
DirectX 9.0c.

If your computer is below these requirements, then the game simply will not start or it will slow down and turn off by itself at some point. It is recommended to have a computer that exceeds these minimum requirements, and the better your system, the more graphics options you can enable without sacrificing gameplay and performance.

How to launch a pirated version of GTA 4

To launch a pirated version of the game, you need to download the image of the game from a torrent or any other resource and a crack for hacking. If after installation the game does not want to start, then you need to:

Remove the game and Games For Windows from the computer completely with all files.
Download the latest version of Games For Windows from the Microsoft website.
Install the game again and install the desired crack.
Go to the "Control Panel" in the "Accounts" section. Click on "Change User Account Control Settings". Set the slider to the very bottom, where it will say "Never notify."
Disable antivirus and firewall on the computer.
Launch the game and check if it works.

Thus, a pirated version of GTA 4 is installed on the computer. However, even with the correct installation of the game, there may be problems with the launch. These issues will be discussed below.

A small review on GTA-4

Almost all Rockstar Games games deserve the highest praise and devoted love from fans. So it happened with GTA-4 - the story of a Serbian immigrant Niko Belik, who decided to seek his fortune in the "City of Liberty" - Liberty City, the prototype of which is New York. The plot, frankly, cannot boast of any innovations in the presentation or exciting twists, but Rockstar managed to tell a good story with memorable characters and its own philosophy. The gameplay has undergone impressive changes for the better since the days of San-Andreas: physics and animation have become more realistic, shooting is more dynamic, and the number of entertaining things to do in your spare time from passing the main line just rolls over. We can take a job from our friends, work as a policeman, have fun with comrades in bowling or billiards, have an affair with a girl, visit an Internet cafe and so on. Of course, no one will stop you from making uniform chaos on the streets, scaring people, stealing cars and fighting cops. In general, GTA-4 turned out to be a wonderful game that can colorize the gray tones of a boring evening. Needless to say, there is also an exciting multiplayer and 2 exciting DLCs? But from pleasant to sad: if you are constantly "chased" by errors starting the game, then read the article below, where we will talk about their solution. So, why doesn't GTA-4 start?

Errors in GTA-4 and how to solve them

It so happened that for the PC the game came out very unoptimized, which gave rise to endless errors, bugs and other shortcomings, forcing the developers to release as many as 7 patches. Unfortunately, sometimes even they are not enough for a comfortable game. If you are wondering about "GTA-4", then read our article. Perhaps she will help you. So, we will analyze in order all the errors that players encounter.

If you get a critical error DD3D10 D3D Error, then just try restarting your computer.
DD3D50- make sure your graphics card supports DirectX-9.
DD3D60- make sure you have support for Shader Model 3 or higher.
AE10 Insufficient Memory to Start Game - try close unnecessary applications, then re-enter the game.
TEXP60- try updating the DirectX libraries or video card drivers.
If your "GTA-4" does not start, knocking out an error RESC10 Out of video memory, - restart your computer/reinstall the game.
RMN20 Windows Vista - make sure you have Service Pack-1 and above installed.
RMN30 Windows XP 64 / Server 2003 - make sure you have Service Pack-2 or higher installed.
RMN40 Windows XP - you need to install Service Pack-3.
If it is impossible to create textures, an error occurs TEXP110 D3D Error. Her solution would be to restart the game.
DWIN20 - about The error is thrown when a conflict occurs when accessing RAM memory. Try restarting the game.
DD3D10/30 - try restarting your computer.
DD3D20- try updating the DirectX libraries or reinstalling the game.
DD3D70 / GPUP10 / TEXP20 / TEXP30 / TEXP80 - errors occur when a D3D device conflicts. Try restarting your computer.
DD3D40- video card conflict. Try up to the latest version.
DD3D80- if "GTA-4" won't start due to this error, just try restarting the game/restarting the computer.
STRB10- The error occurs when uninstalling the file. Try restarting your computer.
RMN10 / STRM10 / STRM20 - The error occurs when there is a file read conflict. Try restarting your computer.
VOIC10- The error is due to a voice chat conflict. Try restarting the game.
BA10 / EA10 - errors occur when full Try restarting the computer.
TEXP60- occurs when a color rendering error occurs. Try installing the latest video card drivers.
TEXP70- occurs when a depth rendering error occurs. See paragraph above.

"GTA-4" does not start on Windows-7/8

This error is quite common among players, but its solution is quite simple. If you are playing on Windows-7, then before installing the game, try making changes to the registry. How? Follow the algorithm: Start => Search => regedit => "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Windows" => "CSDVersion", change its value from "0" to "100" => Restart => Install GTA-4 = > We return the changed values back to "0". If this method does not help, then try the second method, which will be similar to solving the problem of Windows-8 owners (why "GTA-4" does not start on Windows-8): set the properties of the executable to be compatible with Windows XP SP3 (service pack 3) .

Game optimization

We already wrote earlier that the port of the game turned out to be too crooked, which is why GTA-4 optimization is at a deplorable level. And yet it can be slightly improved in terms of performance in order to remove some bugs and increase FPS by 10-20 units. So, try doing the following:

First, update the drivers for all programs that the game uses (Microsoft .NET Framework 3.5 SP1, DirectX, video card drivers, etc.).
At the root of the game, create a text file called commandline.txt. You can write many commands in it, which you will find on the Internet, but it is recommended to write the following: -availablevidmem 2 (number 2 - for video cards with 256 MB of video memory, "3" - 512, "4" - 1024 and so on), which increases the available video memory, which can solve the problem with missing textures; -noprecache (allows you to disable pre-caching of files); -nomemrestrict (allows you to disable the memory limit, although the performance is not too high in this case); -norestrictions (allows you to open hidden settings); -novblank (allows you to disable -minspecaudio (the game starts with minimal sound quality, which significantly reduces the load on the processor). Each command is written on a new line and with a "-" in front of it.
If you have a weak PC, then try to "dig" in the graphic settings. First, turn off shadows and reflections, because they consume a lot of resources. Second, try lowering the quality of the textures. If after these steps you still experience slowdowns, reduce the depth of detail, the density of auto traffic and the viewing distance, which also "eat" the order of resources, albeit not as much as the settings for shadows and reflections. Another setting item that can increase FPS by 5-10 units is "Clip Recording", which must be disabled.
If you have a licensed copy of the game, it will automatically update to the latest version. If a pirated copy is available, install the 4th patch, where the best optimization is observed.
Disable unnecessary applications when entering the game: browser, Skype, antivirus and more. This will reduce the load on the processor and RAM.

If all of the above methods do not help, then you may need to upgrade your computer.

Launching the game on Steam

The first thing to know is that GTA-4 can only be activated on Steam when purchased directly from Steam. If you purchased the game at retail or other online stores, you will need to play through GFWL. There are times when some gamers do not start the "GTA-4" STIM version, but the reasons for this in most cases coincide with the errors described above. If problems occur directly with the Steam service, then simply try restarting it or contact support. Finally, to be clear, even if you buy the game on Steam, you still need to install Rockstar Social Club in order to play the game.

Finally

Rockstar Games is not too loyal to PC players, as evidenced by their policy regarding this platform (delays in the release of PC versions for six months or a year, or complete disregard for it, poor optimization, etc.). So if your "GTA-4" does not start, then do not rush to be disappointed, because almost all errors have their own solutions, which you could see above. Know one thing: GTA-4 is one of the greatest games of the last 5-10 years and is sure to give you many hours of fun.
