The d3dx9_26.dll file is one of a number of files contained within DirectX. Since DirectX is utilized by most Windows-based games and advanced graphics programs, d3dx9_26.dll errors usually show up only when using these programs. Any of Microsoft's operating systems since Windows 98 may be affected by d3dx9_26.dll and other DirectX issues. This includes Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.

How to Fix D3dx9_26.dll Errors Do not, under any circumstances, download the d3dx9_26.dll DLL file individually from any "DLL download site". There are a number of reasons that downloading DLLs from these sites is a bad idea. If you've already downloaded d3dx9_26.dll, remove it from whatever folder you copied it to and then continue with the following steps. Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the d3dx9_26.dll error. Restart your computer if you haven't yet done so. The d3dx9_26.dll error might be a fluke or one-time issue, 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_26.dll not found error. 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. The same DirectX installation program works with all versions of Windows including Windows 10, 8, 7, Vista, XP, and more. It will replace any missing DirectX 11, DirectX 10, or DirectX 9 file. If the latest DirectX version from Microsoft doesn't fix the d3dx9_26.dll error you're receiving, look for a DirectX installation program on your game or application CD or DVD. Usually, if a game or another program utilizes DirectX, the software developers will include a copy of it on the installation disc. Sometimes, though not very often, the DirectX version included on the disc works better with the software 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 d3dx9_26.dll and a reinstall could do the trick. Restore the d3dx9_26.dll file from the latest DirectX package. If the above steps haven't worked to correct your d3dx9_26.dll error, try extracting the d3dx9_26.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. Need More Help?
