Quite often, when trying to turn on any game, a system error appears with a message about the impossibility to launch the executable file due to the absence of the d3dx9_25.dll library or due to its damage. The second happens very rarely, but the problem with the missing file is very relevant for Windows from Microsoft.

What is this mistake

An error that occurs when launching games regarding the absence of this dll on the PC indicates that your version of DirectX is outdated and needs to be updated. In order to resolve the conflict that has arisen, you will need to download d3dx9_25.dll and copy it to the system directory or install the latest version of the system software.

It is a package of dynamically loaded files containing various constants, functions and procedures necessary for the functioning of a huge number of modern games and multimedia applications.

Downloading the missing component

1. Follow the link

to download the missing file.

2. We call the properties dialog box of the "My Computer" folder, where we find the line "System type". We remember to decide where to throw the missing file.

1. We unpack the archive using an archiver or using Windows tools into the system directory:

Without registration, the executable file, for example, GTA San Andreas will not be able to detect the library, therefore we perform the procedure for entering information about it into the system registry.

Enter "regsvr32 d3dx9_25.dll" in the search form of the "Start" menu and press "Enter". Then we restart the computer and play. If the error appears again, copy d3dx9_25.dll to the folder with the game executable file or go to the second option. It will save you from such conflicts with other Yandex.Direct components.

Sometimes, when trying to open a particular game, we encounter an error that appears due to the absence of the d3dx9_25.dll file. Today we will just talk about how to download d3dx9_25.dll for free and fix this error, and we will do this in two ways at once. You will also find out why the problem arises in general and what this dll file is for. Let's get started.

For modern games to run on Microsoft Windows XP, 7, 8, or 10, you need a special DirectX dynamic library. D3dx9_25.dll is just a component of such a package. What happens if DirectX is not installed on the PC or does not contain one of the drivers? Events will occur according to the following scenario: the game, for example, GTA San Andreas will start to start, request access to the dynamic dll-library and, finding that it is not there, will give an error.

After reading this, some users have a question - why is such a file sometimes missing? We answer: there are several reasons for this at once. For example, DirectX is simply not installed on your computer. Also, most people use pirated versions of games, the multimedia components of which may have been damaged during repackaging. Sometimes the required dll file can be damaged by a virus. But in all these cases, the result is the same - the game does not start and gives an error.

Ways to solve the problem

To add d3dx9_25.dll to the system and thus allow all games to work, you can use two options at once. The first involves installing the entire dynamic link library, and hence the dll files it needs, including our d3dx9_25.dll. The second method involves loading just one file and then adding it to the OS file system.

And if the first method guarantees almost one hundred percent success of the subsequent launch of any games, the second works only in some cases. The fact is that just adding files to the system is not enough, they need to be registered, and this is not always possible. If one or more DLL components are missing, the game will not start after all the efforts.

Download the Microsoft DirectX library

Let's consider an option that helps in most cases. We will install all the dll files necessary for the functioning of any games, and with them d3dx9_25.dll. In order to do this, download the file from the direct link and run the WEB-installer.

1. After it is downloaded, run the file and follow our prompts. Initially, you need to switch the trigger to the position that we marked in the figure with the number "1". We thereby accept the license agreement. When everything is done, click on "Next".

1. Microsoft offers us to download additional software (we have this Bing panel): in this case, uncheck the box marked with the number "1" in the screenshot and click "Next" again.

1. The DirectX installation has started. Since all the necessary files, or rather, their latest versions, are downloaded from Microsoft servers, the installation speed may vary. Everything took us about one minute.

To find out the bit depth of your system, simultaneously press the Win + PauseBreak buttons on your keyboard and look at the area that we marked in the screenshot.

1. When the file, depending on the bitness, is placed in the Windows folder, copy it to the directory with the game. This is not always necessary, but to be on the safe side, let's do just that. You need to copy d3dx9_25.dll to the game folder, which contains the executable components. In our case, this is World of Tanks and the root directory. There are files with the .exe extension that start the game.

1. Now that all the files are in place, you need to register them. To do this, you can use both the command line with PowerShell and the Run tool. We will use the latter option. We launch the utility using the Win + R hotkey combination and enter the command into it: regsvr32 d3dx9_25.dll Then click "OK".

Sometimes dll registration fails. This is due to other components, which, like d3dx9_25.dll, are missing in the system. If so, use the DirectX installation method.

After the files are added to Windows and we register them, you can try to start the game itself, but before that, be sure to restart your computer or laptop.

Additional Information

Above, we considered two ways to solve the problem related to the absence of the d3dx9_25.dll file at once. You also learned how to download and install it for free without having to install all of Microsoft DirectX. If you still have questions after reading what you have read, ask us in the comments and we or other users will help in this or that situation.

Video

To complete the picture, we have prepared for you a video similar in topic, which describes the process of solving the d3dx9_25.dll error.

Sometimes d3dx9_25.dll and other DLL system errors can be related to problems in the Windows registry. Several programs can share the same d3dx9_25.dll file, but when these programs are uninstalled or changed sometimes orphaned (invalid) DLL registry entries are left behind.

Basically, this means that while the actual path to the file may have changed, its incorrect former location is still recorded in the Windows registry. When Windows tries looking up these incorrect file references (file locations on your PC), d3dx9_25.dll errors can occur. In addition, malware infection may have corrupted the registry entries associated with Microsoft® DirectX for Windows®. Thus, these invalid DLL registry entries need to be repaired to fix the root of the problem.

Manually editing the Windows registry to remove invalid d3dx9_25.dll keys is not recommended unless you are PC service professional. Errors made while editing the registry can cause your PC to malfunction and cause irreparable damage to your operating system. In fact, even a single comma in the wrong place can prevent your computer from booting!

Because of this risk, we highly recommend using a trusted registry cleaner such as WinThruster (Developed by Microsoft Gold Certified Partner) to scan and repair any d3dx9_25.dll-related registry problems. Using a registry cleaner automates the process of finding invalid registry entries, missing file references (like the one causing your d3dx9_25.dll error), and broken links within the registry. Before each scan, a backup is automatically created, allowing you to undo any changes with one click and protecting you from possible damage to your computer. The best part is that fixing registry errors can dramatically improve system speed and performance.

A warning: Unless you are an experienced PC user, we do NOT recommend manually editing the Windows registry. Incorrect use of Registry Editor can lead to serious problems and require you to reinstall Windows. We do not guarantee that problems resulting from improper use of Registry Editor can be fixed. Your use of the Registry Editor is at your own risk.

To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to d3dx9_25.dll (eg.Microsoft® DirectX for Windows®):

1. Click on the button To begin.
2. Enter " command" in search bar ... DO NOT PRESS YET ENTER!
3. Holding the keys CTRL-Shift on the keyboard, press ENTER.
4. A dialog box for access will be displayed.
5. Click on Yes.
6. The black box opens with a blinking cursor.
7. Enter " regedit" and press ENTER.
8. In the Registry Editor, select the d3dx9_25.dll-related key (eg.Microsoft® DirectX for Windows®) you want to back up.
9. On the menu File choose Export.
10. In the list Save to select the folder where you want to save the Microsoft® DirectX for Windows® backup key.
11. In field File name type a name for your backup file, such as "Microsoft® DirectX for Windows® Backup".
12. Make sure in the box Export range value selected Selected branch.
13. Click on Save.
14. The file will be saved with the extension .reg.
15. You now have a backup of your d3dx9_25.dll-related registry entry.

The next steps for manually editing the registry will not be described in this article, as they can most likely damage your system. If you would like more information on manually editing the registry, please see the links below.
