DirectX is a set of components in Windows that allows software, primarily and especially games, to work directly with your video and audio hardware. Games that use DirectX can use multimedia accelerator features built-in to your hardware more efficiently which improves your overall multimedia experience.

If your PC doesn't have the right version of DirectX installed (the product box should tell you which one you need), your game might not work properly.

Checking your version

Follow these steps to use the DirectX Diagnostic Tool to check your DirectX version:

In theSearch box on the toolbar, enterdxdiag. Then selectdxdiagfrom the list of results.
In theDirectX Diagnostic Tool, select theSystemtab, then check the DirectX version underSystem Information.

Note: The first time you use the DirectX Diagnostic Tool, you might be asked whether you want to check if your drivers are digitally signed. We recommend that you selectYesto help ensure that your drivers have been signed by a publisher that has verified their authenticity.

Updating DirectX

To get the latest version of DirectX for your version of Windows, useWindows Update. If you have Windows 10 or 11, then you already have the latest version of DirectX installed.

Note: Not all versions of Windows can run the latest versions of DirectX.
