About Visual C++ Redistributable Package for Visual Studio 2008
These packages install runtime components of C Runtime (CRT), Standard C++, ATL, MFC, OpenMP and MSDIA libraries. For libraries that support side-by-side deployment models (CRT, SCL, ATL, MFC, OpenMP), they are installed into the native assembly cache, also known as the WinSxS folder, on versions of Windows operating systems that support side-by-side assemblies.
