Windows 7 VPC and x64 guest

Discussion in 'Virtual PC' started by John Straumann, Jul 27, 2009.

  1. Hi all:

    I am trying to install a 64-bit guest OS on Windows 7 x64 RC and Virtual PC.
    I have enabled virtualization in the BIOS, but when I try to install I get
    an error screen with:

    "Attempting to load a 64-bit application, however this CPU is not compatible
    with 64-bit mode"

    but the CPU IS so I am wondering if anyone out there has seen this?

    Thanks.

    John.

    Virtual PC doesn't support 64-bit guests.

    It's been seen and posted about time and time again, VPC doesn't support x64
    guests.

  4. Thanks for your response, Robert. That's a simple but unhappy answer, I
    assumed that restriction was removed with Windows 7....

    It isn't Windows 7 that's the problem, it's the virtual PC application, no
    matter what OS you run it on it doesn't support x64 operating systems,
    Windows Virtual PC for Windows 7 does, if your PC meets the hardware
    requirements http://www.microsoft.com/windows/virtual-pc/

    I
    Unfortunately not, you would need to go with some other virtualization
    software, either Windows Server with Hyper-V from Microsoft or
    something like VMWare Workstation.

    Is it? Could have swore they finally had x64 guest support, my bad.

    Yep. Virtual PC for Windows 7 is purely targeted at the legacy app
    market so you can move to Windows 7. (it actually does that quite
    well!) It did add USB support.

    Actually, it doesnt work in XP mode's version of virtual PC either. I'm using Win 7 x64, with an E6300 CPU, which supports VT. And you get the same message
