@DanielB as I mentioned in my question earlier, I'm running Windows 8.1 that ALREADY comes with DirectX 11 and DirectX End-User Runtime 9.0c isn't even compatible with Windows 8.1.
The short answer is you can't install "DirectX" on Windows 7. It comes with DirectX 9.0c, DirectX 10, and DirectX 11 already. The DirectX End-User Runtime therefore never installs "DirectX" on any version of Windows newer than Windows XP Service Pack 2. It does, however, still install some of the optional (and largely deprecated) utility bits like D3DX9, D3DX10, D3DX11, etc. See KB79113 under ...
