Fixing 3D errors: caring for your favorite Sims characters starts in real life

So, if a system error appears “the program cannot be started...” you just need to add the missing file that is so important for the OS - d3dx9_31.dll. This software component is an integral part of the API set in DirectX; in its absence, important graphics operations cannot be performed.

• Specifically, you can download the missing fragment of the main DirectX library to your computer.

• Next, the downloaded d3dx9_31.dll file should be unzipped and moved to the system directory - “system32”.

• Sometimes the OS requires that the mentioned DLL file be also accessible from the Game folder and located in one of its bin subdirectories.

And finally...

Often, when copying or pasting a missing DLL component, the operating system ambiguously offers to replace the existing file - we agree to the changes being made. If you do everything according to the above recommendations, your Sims 3 will come to life again. Have a pleasant and exciting gaming session!

Sometimes a powerful computer may not be enough to run a game, and you have to work hard before finally playing the desired new product. It is worth noting that only the resources of your computer may not be enough for this, because some additional files may be needed. Such as codecs, drivers for various equipment, etc.

One of the most common errors is the absence of certain libraries in the system partition, in particular d3dx9_31.dll. This is not critical for the operation of the computer, but without this file many new games simply will not start. Often, the game comes with a set of software necessary for its correct operation, but its versions may be outdated.

To fix the problem, you need to download d3dx9_31.dll yourself. This file can also be downloaded for free for The Sims 3. This article provides detailed instructions on where to throw the downloaded file, and what to do if this error occurs.

Method one - manual

If, when starting the game, the system displays the error “d3dx9_31.dll...”, then the reason is probably the following:

1. The module loaded, but the entry point could not be found.
2. The file does not exist on this computer.
3. The file was deleted or an outdated version was installed.

You can download the file without SMS and registration. And of course, without viruses and other unwanted software that is installed in a mode hidden from the user.

After downloading, the file will simply need to be moved to the C:\Windows\SysWOW64\ folder if the computer has 64-bit Windows 7, 8 or 10.

If 32-bit is installed, then just go to the System32 folder.

In some cases, copying may require administrator rights, and if you are working under a guest account, you will not be able to copy the file.

Copying the file may take some time, and your computer may not be able to be turned off or restarted. After moving the library, you must manually register it from the command line.

To do this, type CMD in the Start menu search field and press enter. Then enter “regsvr32 d3dx9_31.dll” and confirm. That's all, registration can be considered completed and the applications will work correctly again.

It is also important to regularly update your computer software from Windows Update and create backup system restore points to correct possible problems. After completing copying and registration, it is advisable to restart the computer.

Method two - automatic installation

You can also try to get rid of such an error in the old and proven way - in a new way. This is a complete set of libraries for the correct operation of games and multimedia programs.

On our website you can always find its latest and most current version.

Each of you has probably encountered the d3dx9_31.dll error on your computer at least once. In an attempt to solve the problem, a person searches for the missing file on the network and often downloads a virus to the PC or laptop. In this article we will tell you how to safely download d3dx9_31.dll and correctly add it to the system.

The file belongs to the Microsoft DirectX library, which is needed for rendering 3D graphics in games, for example, Sims 3, GTA 4, etc. If one or more components are missing, naturally, the game will not start, and the user will see the following message: The program cannot start because d3dx9_31.dll is missing . In most cases, the error appears due to DirectX being completely missing, or sometimes one of its components is damaged. Below we will look at what it is, what the problem is, how to fix it and launch the game we need.

Solving the problem

There are two ways to fix the situation: install DirectX or add its missing component. The first method is preferred, but for completeness, we will describe both of them.

Attention! Use the file option only if the game does not start after reinstalling DirectX.

Installing DirectX

Let's fix the error when starting the game by installing Microsoft DirectX. This library contains all the dlls necessary for any game to work, including ours.

1. To get started, download the official software installer and run it. Here we will be asked to accept the license of use - to do this, check the radio button as we did in the screenshot. We strongly do not recommend searching for DirectX on the Internet. There are a lot of fakes that will install a bunch of unnecessary software or, even worse, a virus on your computer.

1. Here we need to remove the small, invisible checkbox that tends to download and install unnecessary software on our computer. When this is done, click on “Next”.

As a result, the library, and along with it all the necessary components, will be downloaded and installed on the PC. All that remains is to try to launch the game. Sometimes you also need to restart your computer for the changes to be applied.

Download and install the d3dx9_31.dll file separately

This method does not guarantee the successful launch of the game. There is only a small chance that after adding the file to the system directory and to the game folder, the latter will start working. Still, we have no right not to mention an option that, at least theoretically, can lead to success.

1. First of all, download it to your computer or laptop. The archive has a .zip extension, so you don’t need an archiver to open it - any Windows operating system can handle it. We extract the file depending on the bit depth of the system and put it in a convenient place. Next, copy the required component to the system directory of Windows XP, Windows 7, Windows 8 or Windows 10.

If you have an x32-bit system:

x64-bit system:

To determine the bitness of your system, use the keyboard shortcut Win + PauseBreak. In the window that opens, you will see the architecture of the operating system (indicated in the screenshot with a red frame).

1. Now copy the downloaded file to the game folder. Place it in the directory that contains the .exe files that run it. After this, you need to register the components. We will do this through the command line. In Windows 10, you can open it through search. To do this, click on the magnifying glass icon and enter the word in the search bar cmd . We right-click on the result that appears and select the section indicated in the picture with the number “3”.

After applying the changes, be sure to restart your PC and only then try to launch the game.

Let's sum it up

In the article, we told you where to download d3dx9_31.dll for free and how to correctly install it on the system as a single file and a Microsoft DirectX library. If you have any difficulties or just want to ask us a question, write it in the comments - we will definitely help every user.
