Trying to install Virtual OS of XP 64bit on Vista 64bit, ERROR stating CPU is not 64bit — at Initial Version

Reported by: dhitchner Owned by:
Component: other Version: VirtualBox 2.1.0

Description

The message I am getting is:

"Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bit X86 operating system.

Setup cannot continue. Press any key to exit."

My host operating system is Windows Vista 64-bit. My CPU is definitely a 64-bit CPU. I've even had XP 64bit on this computer before. As far as I know, I did everything fine up to this point. I selected XP 64bit as the opperating system to be installed. I gave it 4 Gb of RAM and 125Gb of HD space.
