Microsoft DirectX is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full- color graphics, video, 3D animation, and rich audio.

DirectX 9.0 includes security and performance updates, along with many new features across all technologies, which can be accessed by applications using the DirectX 9.0 APIs. DirectX 9.0 End-User Runtime setup minimizes the download size but requires an internet connection during setup. The DirectX 9.0 Redist is available for download for those users that do not have an internet connection available during installation or Setup has trouble connecting to the Microsoft server. This download provides the DirectX 9.0c end-user multi-languaged redistributable that developers can include with their product. The redistributable license agreement covers the terms under which developers may use the Redistributable. For full details please review the DirectX SDK EULA.txt and DirectX Redist.txt files located in the license directory.
