Reinstalling DirectX

To reinstall DirectX, insert the CD (Compact Disc) containing the DirectX version you want to reinstall, and search for the appropriate file. Or, locate the recently downloaded DirectX file on your computer. Once found, double-click the file named "dxsetup.exe" and choose the option to reinstall.

We do not recommend you attempt to install an older version of DirectX over a newer version, unless the older version is completely uninstalled.
