Check Direct X Version

DirectX is Microsoft's name for a family of application programming interfaces designed to speak to multimedia programs, such as music and video players. The DirectX family includes Direct3d, DirectMusic and DirectPlay and the "X" stands in for the name of the individual program. In addition to applications in the Windows operating system, Microsoft also uses DirectX in its Xbox video game system. Older versions of DirectX may not work with newer multimedia applications. If you find yourself receiving errors in your multimedia programs, you may need to check your Direct X version to determine if you are up-to-date.
