Cause of D3dx9_26.dll Errors

Unlike many other dll errors which can have complicated causes and fixes, d3dx9_26.dll issues are caused in one way or another by a single issue - a problem of some sort with Microsoft DirectX.

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.

Troubleshooting Steps

Important Note: Do not, under any circumstances, download the d3dx9_26.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_26.dll from one of those DLL download sites, remove it from whatever folder you copied it to and then continue with the following steps.

  1. 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.
  2. 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.

    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.
  3. 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 other 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.
  4. 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.
  5. 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.
  6. 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.

Applies To

The d3dx9_26.dll error message could apply to any program that utilizes Microsoft DirectX, most commonly video games.

Some common games and other programs that have been known to generate d3dx9_26.dll errors include Civilization IV, Autodesk 3ds Max, pSX Emulator (a Sony Playstation emulator), and more.

Any of Microsoft's operating systems since Windows 98 may be affected by d3dx9_26.dll and other DirectX issues. This includes Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
