Checking your version
DirectX is a suite of multimedia technologies required by many Windows games. 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.
-
To check which version of DirectX is on your PC using the DirectX Diagnostic Tool, select the Start button and type dxdiag in the search box, then press Enter.
-
In the DirectX Diagnostic Tool, select the System tab, then check the DirectX version number under System Information.
-
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 select Yes to 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, use Windows Update. If you have Windows 10, then you already have the latest version of DirectX installed.
Not all versions of Windows can run the latest versions of DirectX.
