So, why does Wind River keep dropping the ball on this one? What component of their software is so difficult to validate on 64-bit Windows? They've had six years (plus beta time) to figure this out—and even if we generously assume that they only started development when FRC moved to the cRIO-based system, you would think that they would have seen 64-bit operating systems as an inevitability.
Then again, for those who have used it on a 64-bit OS, my recollection is that there haven't been any issues. (The permissions issue mentioned above doesn't seem to be 64-bit-related. Incidentally, requiring software to run as an administrator is usually something of a blunder as well.)

And also consider the capabilities of the laptop. I know that those things have Intel Atom processors that do 64-bit processing, but also consider that it does take up more RAM power. For 64-bit, I always recommend 2GB for good performance because 1GB is going to fill up straight away and leave you with 25-30%resources for whatever you want to do. How do I know?: I'm a computer technician.

All 64-bit consumer versions of Windows from Windows XP x64 onward have native support for 32-bit code in a
built-in subsystem. The software doesn't need specific compatibility with 64-bit Windows to run. (The issue above is that Wind River hasn't yet declared it compatible—so it might work, but Wind River won't guarantee anything about that configuration.)
The hardware type won't matter, either, at least on any common PC. The 32-bit x86 instructions are natively supported on 64-bit processors like Atom and Core.
Also, I think you're confusing the fact that 64-bit systems can address more RAM than 32-bit ones with an actual need for significantly more RAM. (Yes, the addresses are longer, but that's about it!)
(For more detailed information on computer architecture, I think it might be worthwhile for you to check out the
Tech Report and
Ars Technica; their articles are generally quite thorough, and would serve you well as a computer technician.)
