How to Fix D3dcompiler_43.dll Errors

Do not download the d3dcompiler_43 DLL file individually from any "DLL download site". There are several reasons that downloading DLLs from these sites is never a good idea. If you've already done so, remove it immediately and continue with these steps.

  1. Restart your computer if you haven't yet. The d3dcompiler_43.dll error might be a fluke, and since restarting is a common fix for lots of computer problems, it could clear up this DLL error completely.

  2. Install the latest version of Microsoft DirectX. Chances are, upgrading to the latest version will fix the error "d3dcompiler_43.dll not found," but if not, try DirectX End-User Runtimes (June 2010) instead.

    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 program works with all versions of Windows and will replace any missing DirectX file.

  3. Assuming the latest DirectX version from Microsoft doesn't fix the error you're receiving, look for a DirectX 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 disc. Sometimes, though not often, the version included on the disc is a better fit for the program than the latest version available online.

  4. Reinstall the game or software program. Something might have happened to the files in the program that work with d3dcompiler_43.dll, and a reinstall could do the trick.

    If this doesn't work, it's possible that not all the program files were actually deleted, or that some registry entries related to the DLL file remained, and that's what's causing the error even after reinstalling the software. Try again with a free uninstaller tool and see if that doesn't do the job.

  5. Restore d3dcompiler_43.dll from the latest DirectX software package. If the above troubleshooting steps haven't worked to solve your error, try extracting the DLL file individually from the DirectX downloadable 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.
