Cause of D3dx9_25.dll ErrorsD3dx9_25.dll issues are caused in one way or another by a single issue - some kind of problem with Microsoft DirectX.
The d3dx9_25.dll file is one of many files that make up the DirectX software collection. Since DirectX is utilized by most Windows based games, d3dx9_25.dll errors usually show up only when using these programs.
Troubleshooting StepsImportant Note: Do not, under any circumstances, download the d3dx9_25.dll DLL file individually from any "DLL download site." There are a number of different reasons that downloading DLLs from these sites are never a good idea.
Note: If you've already downloaded d3dx9_25.dll from one of those DLL download sites, remove it from wherever you copied it to and continue with the these steps.
- Restart your computer.
The d3dx9_25.dll error might be a one-time problem and a simple restart could clear it up completely. It's unlikely this will fix the problem, but restarting is always a good first troubleshooting step.
- Install the latest version of Microsoft DirectX. Chances are, upgrading to the latest version of DirectX will fix the d3dx9_25.dll not found error.
Note: Microsoft often releases updates to DirectX without updating the version number or letter so be sure to install the latest release even if your version is technically the same.
Note: The same DirectX installation program works with all versions of Windows including Windows 7, 8, Vista, XP, and more. It will replace any missing DirectX 11, DirectX 10, or DirectX 9 file.
- Assuming the latest DirectX version from Microsoft doesn't fix the d3dx9_25.dll error you're receiving, look for a DirectX installation program on your game or application CD or DVD. Usually, if a game or other program utilizes DirectX, the software developers will include an installable copy of DirectX on the setup disc.
Sometimes, though not often, the DirectX version included on the disc will work better with the program than the latest version available online.
- Uninstall the game or software program and then reinstall it again. Something may have happened to the files in the program that work with the d3dx9_25.dll file and a simple reinstall could do the trick.
- Restore the d3dx9_25.dll file from the latest DirectX package. If the above troubleshooting steps haven't worked to solve your d3dx9_25.dll error, try extracting the d3dx9_25.dll file individually from the DirectX package.
- Update the drivers for your video card. While it's not the most common solution, in some situations updating the drivers for the video card in your computer could correct this DirectX issue.
