Generally speaking, VS2008 SP1 contains VC++ MFC 2008 feature pack. If you have already installed VS2008 Sp1, you don’t need to install
VC++ MFC 2008 feature pack.
In Visual studio, we are allowed to develop the application which targets to different platforms (X64, X86, etc).
For the Visual Studio 2008 itself, it is a 32 bit product. We don’t have 64 bit Visual Studio.
As a recommendation, please install Visual Studio 2008 SP1, which covers MFC feature package and other updates. You can download and install it
If you have any concerns, please let me know.
