Host OS: Windows 7 Ultimate 64-bit

Visualization software: Microsoft Virtual PC Version

From the googling I have done it would appear that Microsoft Virtual PC does not support 64-bit guests. Google: "64bit guest windows virtual machine".

Try using a different virtualization software such as VMWare.

I am running version on the virtual machine. I Googled to seed if this version was compatible, but I'm beginning to think you're correct. I'll mark this as the answer as soon as I do some more research. – Holyfallen Sep 24 '13 at 19:07
