- Launch the installer to get started, then select that you agree to the terms before clicking Next.
- The DirectX installer will ask you if you want to install the unnecessary Bing search bar. We wouldn't recommend this, so uncheck the box and click Next.
- The installer will confirm that DirectX must be installed, along with the file size. Click “Next” to continue.
- At this point, the installer will download and install the required components. Please wait a while for the installation to complete. Once the installation is complete, click Finish to exit.

How to find out your Steam id? Why is it needed?
At the beginning of the article it was said that the Steam id is closely related to Counter Strike 1.6, but for what reasons is this id used? The answer is quite simple: in the above game there are servers, it is within the framework of Counter Strike that they are quite developed, because they have their own admin, who can incredibly change the gameplay. There are moderators with authority over regular players. Everything functions quite smoothly until one of the people starts doing nonsense, for example, using prohibited software - cheats.
You need to exclude an unwanted person from the server, and you block his IP address, but time passes, and he comes in again, simply changing his address. Steam ID blocking comes to the rescue - this is a special identity authenticator that is issued once, but it can also be changed, more on that later. If a person plays with a licensed copy of the game, then he will not be able to log in unless he performs a certain kind of manipulation.
There are times when it is necessary to return a person to the server, even if he behaved inappropriately. Then you will also have to use id.
Instructions on how to find out your Steam id:
- Activate the official Steam application.
- Go to your personal profile and right-click on the avatar and select the last item “view source code...”
- A notepad will open in front of you, where there will be many different HTML tags. Among them you need to find your id. To do this, press the key combination CTRL+F and enter Steamid together. The found string will indicate with an equal sign to your id, which is in quotes.
After these events, you can safely share your Steam ID with your friends, acquaintances and other people who need it for some purpose.
How to fix dysfunction without the Internet
If your computer or laptop is not currently connected to the Internet, then you can fix the d3dx9.dll problem in another way. But for this you will definitely need the installation image of the game (or a folder with files, if it is a repack).
How to run the installation image, read here:
Mount the installation image or open the game folder and find the folder called “Redist”.
This is where the DirectX (as well as Microsoft Visual C++) installation file is located. Launch it and install.
The error cannot be resolved: what should I do?
If DirectX installed successfully, the error “The program cannot be started, d3dx9_31.dll is missing” should disappear. Although sometimes there are problems: a failure occurred during installation or the problem did not go away after it. In this case, there is one more option:
- Launch the game.
- Write down the exact name of the file in the error (or take a screenshot if it closes quickly).
- Find this file in Google or Yandex by name and download it.
But don't forget about precautions. Many sites offer similar files, but they may contain viruses
To avoid infecting your PC or laptop with them:
- make sure it has a DLL extension (the .EXE installer most likely contains a virus);
- check the size - on average it should be 2-4 MB;
- check it with an antivirus as soon as you download it.
After this, the saved file must be copied to the desired folder. Where to throw? There are 2 options here:
- C:\Windows\System32 – for 32-bit Windows;
- C:\Windows\SysWOW64 - for 64-bit Windows.
By the way, most often it appears after reinstalling Windows 7 (after all, all data on the local drive C is deleted) or when purchasing a new PC or laptop (which is essentially the same thing). Therefore, if you bought a new computer or reinstalled Windows, in addition to browsers, antiviruses and other programs, be sure to install DirectX. Save your nerves and time.
