How to Fix D3dx10_35.dll Errors
Follow these steps in the order they're given below to try the more likely fixes first.
Don’t download d3dx10_35.dll individually from any “DLL download site.” From covering up a larger problem to infected files, there are a number of reasons why downloading DLLs from sites like that is never a good idea. If you’ve already done so, remove the file from wherever you put it and continue with these steps.
Restart your computer if you haven’t already. The d3dx10_35.dll error might be a fluke and a simple restart could clear it up completely.
Install the latest version of Microsoft DirectX. Chances are, upgrading to the latest version of DirectX will fix the d3dx10_35.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.
Assuming the latest DirectX version from Microsoft doesn't fix the 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 often, the 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 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.
