Folder Guard is for Windows 7, Vista, XP, and similar versions of Windows (such as Windows Media Center Edition). It is also backward compatible with Windows 2000. Both 32-bit and x64 editions of Windows are supported. Folder Guard is NOT compatible with Windows 95, 98, Me, Windows NT 4.0 or any older version of Windows.

There are no special requirements or recommendations except the obvious one: the better processor and more RAM your computer has, the better Folder Guard will perform.
