I think what kryo means to say is, you'd better wait for the demo before you buy.

I'd be hesitant to even say that, because even if the demo works, if something later changes and breaks the game in XP64, it's not going to be a priority to fix that unless it's also an issue on other versions which we do support.

XP64 is really poorly supported in general so the best option is definitely to upgrade to 7x64 if you can.

I will look into that, thanks for the advice, greatly appreciated:)

No, Vista x64 is supported.

God, this thread scared the pants out of me. Just bought a copy for me and my wife and missed that the thread was concerning XP 64-bit and not win-7 64bit which I got

Ya but the problem with the future is that it's not always here
But I guess I shouldn't have been supprised that Stardock would support my OS. I guess that xp-64 bit was something of an anomaly. M$ was a bit too early.

They weren't too early, they just failed to push or support it (and since they didn't push it, most other companies didn't support it either). Mainstream 64bit OSes have been long overdue.
