  • Restart your computer if you haven’t yet. The d3dx11_43.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 d3dx11_43.dll not found error.
  • The same DirectX installation program works with all versions of Windows and will replace any missing DirectX file.
  • 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 d3dx11_43.dll error you’re receiving, look for a DirectX installation program on your game or application DVD or CD. Usually, if a game or ​another program utilizes DirectX, the software developers will include a copy of it on the installation disc.

  • Uninstall the game or software program and then reinstall it again. Something might have happened to the files in the program that work with d3dx11_43.dll and a reinstall could do the trick.
  • It’s sometimes best to use a free uninstaller tool to make sure the program has been completely removed before you reinstall it.

  • Restore the d3dx11_43.dll file from the latest DirectX software package. If the above troubleshooting steps haven’t worked to solve your error, try extracting the d3dx11_43.dll individually from the DirectX downloadable package.
