Update: Please note that the REDIST folder for the DirectX SDK (June 2010) is slightly out of date now. You should make use of the refreshed version of DirectSetup if you need the REDIST.

Known Issues: Be sure to read this article for known issues trying to install the DirectX SDK (June 2010) due to a problem with the Visual Studio 2010 CRT.

Note: The DirectX SDK is now legacy. You should use the Windows 8.1 SDK instead, or at least prefer the Windows 8.1 SDK over the legacy DirectX SDK as much as possible.
