Attached Link: Microsoft Windows XP Professional x64 Edition

Mindy: you're very welcome, glad I could help :)

Rick: the 64's you're referring to is indeed the new Windows Vista which has been delayed. However there's a 64 bit Windows XP version available, from which you can download a trial version at MS, but as I've said before, there aren't many (good) 64 bit drivers available yet and I'm not sure if UF will benefit from the 64 bits, or fall back to the good old 32 bits in which case you won't have much adavantage from the 64 bits. If you're bold enough to try it out, I'd advice you to make a dual boot, ie your 32 bit version and the new 64 bit version of XP.

(I just read this on the UltraFractal home page: A 64-bit version of Ultra Fractal is not currently planned.)
