If you are running a 64-bit version of Windows (which is almost everyone today), you can run both 64-bit and 32-bit programs. If you try to run an older 32-bit game on your modern 64-bit PC, that game needs the version of the redistributable. If you run a modern 64-bit video editor, it needs the x64 version.
