Troubleshooting Steps

Do not download the d3dx10_35.dll DLL file individually from any "DLL download site." From covering up a larger problem to infected files, there are a number of excellent reasons that downloading DLLs from these sites are never a good idea.

If you have already downloaded d3dx10_35.dll from a DLL download site, you can remove it from wherever you put it and continue with these steps.

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.

Windows 7, 8, 10, Vista, XP, etc. are all supported by this same DirectX installation package. It will install any DirectX 11, DirectX 10, or DirectX 9 file needed and supported in that version of Windows.

  • Assuming the latest DirectX version from Microsoft doesn't fix the d3dx10_35.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 DirectX on the installation disc.
    • Sometimes, though not often, the DirectX version included on the disc is a better fit for the program than the latest version available online.
  • Uninstall the game or software program and then reinstall it again. Something might have happened to the files in the program that work with d3dx10_35.dll and a reinstall could do the trick.
  • Restore the d3dx10_35.dll file from the latest DirectX software package. If the above troubleshooting steps haven't worked to solve your d3dx10_35.dll error, try extracting the d3dx10_35.dll individually from the DirectX downloadable 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.
