Virtual PC no support 64 bit OS??

I wanted to install Vista to do a couple of tests. I don't have any spare machines, so I thought I'd install in a virtual machine under Windows 7. Windows Boot Manager gave me his message:

"Attempting to load 64 bit application, however this cpu is not compatible with 64bit mode."

Of course my computer is ok with 64bit (my primary OS is Win 7 64 bit).

Is Microsoft VPC not compatible with 64 bit guest systems?

You may have a virtualization option that must be turned on in the BIOS. I do.

I am already running Windows XP Mode, so that should not be an issue. Right?

I don't know. The instructional material I read said to be sure it was switched on, so I did so.

Sorry, I just found the answer to my question. Unfortunately 64-bit guest OS is not supported. Look here:

VPC and 64-bit Guest support...

I might have to turn to virtualbox.

Sorry to tell you but Virtual PC does not support 64-bit guest operating systems. If you want to install a x64 OS on a virtual machine you can use Sun VirtualBox. Free download here.

Indeed, you read my mind. See my post of a few seconds ago. This is sooo like Microsoft.
