Reinstall DirectX for troubleshooting

If the problem persists, you can reinstall the DirectX runtime environment . To do this, download the latest version of DirectX and follow the necessary steps for installation .

Uninstall the affected program

When running a program or a game application, the files of the software that are trying to work with the DLL files may be corrupted. This can lead to an error message. However, you can fix the problem by first uninstalling the software and then reinstalling it . When uninstalling, pay attention to files that the program may have stored on your computer, so-called registry entries . You can use Geek Uninstaller software to completely remove a program from your hard drive..

Perform a manual Windows update

Finally, you can try to solve the problem by manually updating your Windows operating system. DirectX is a Microsoft application and is therefore automatically included in the Windows update. In this post we will show you how you can update Windows manually.
