The VersionNT64, Intel64, and Msix64 properties are all imprecisely and
inaccurately worded, which makes it very difficult to work out how to
use them properly. It's a while since I wasted a chunk of time
experimenting to work out what they actually mean, but I'm fairly sure
that Msix64 being defined actually means that you are running on an x64
edition of Windows. Its documentation implies that you could be on a
32-bit or x64 edition running on an x64 processor, or on an Itanium
processor, but it's wrong.
