I need to test if DirectX9 is intalled on a machine with C# code. Directx 10 and 11 are part of the OS but 9 must be user installed. I need it for multimedia display.

As descripted on (Clickety[^]) You can check for the Registry key HKEY_LOCAL_MACHINE\Software\Microsoft\DirectX.

To get the DirectX version read "Version" string in the same location. If the key does not exist - There is not DirectX installed at all.
