DirectX is a suite of multimedia technologies required by many Windows games. If your computer 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.

Watch this video to learn how to check which version of DirectX is on your computer (0:38)

To check which version of DirectX is on your computer

Open DirectX Diagnostic Tool by clicking the Start button , typing dxdiag in the search box, and then pressing Enter.
Click the System tab, and then, under System Information, check the DirectX version number.

Note

If this is the first time you’ve used the DirectX Diagnostic Tool, you might be asked whether you want to check if your drivers are digitally signed. We recommend you click Yes to ensure that your drivers have been signed by a publisher that has verified their authenticity. For more information, see How can I decide which drivers are safe to install?

To download the latest version of DirectX, see Diagnosing basic problems with DirectX.
