Finding the Version of DirectX on your computer

  • PrintPrint
This document pertains to computers that came with Windows 8, 7, Vista, or XP.
Microsoft DirectX is Windows software technology designed to enhance multimedia experiences, such as 3D gaming, graphics, network gaming, and audio.
Many game and graphic software applications require an installation of a particular version of DirectX. To avoid problems you should not attempt to install an older version of DirectX. The only versions you should install are later versions. For example, If your computer has DirectX 9.0c and a game requires DirectX 7, do not attempt to install DirectX 7. The game should still function properly with the latest version of DirectX.
To find the DirectX version, use the DirectX Diagnostic software tool to find the version number listing in the System Information of the System tab.
NOTE: Visit Microsoft's Web site to find and install the latest version of DirectX, if needed.
