  1. Hello dckopp;

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

    So what's up after that?
  2. 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.

    No. Windows Virtual PC and Windows XP Mode was designed to help small business with application compatibility from Windows XP to Windows 7. The majority of business applications currently run on 32-bit versions of
