Hello dckopp;

I got no idea what you're saying.
Your have Win7 64 installed.

So what's up after that?

Your Widnow XP 64 bit need to be installed on a PC with CPU with 64 bit support. Since you are running it on a VM, I recommend you to check the VM settings as well as go to bios and check VT-d and VT-x is on.

If I am understanding you correctly, you are trying to install Windows XP 64 bit in Virtual PC? That is not possible, as it will only accept 32 bit OS.
