After installing the 2 files for Windows 7 Windows XP mode, the Start Menu now has

Windows Virtual PC
Windows XP Mode

but clicking on the first merely brings out a folder, and clicking on the second brings out a dialog box that says: "Require Hardware Assisted Virtualization"

Does that mean the machine cannot support Windows 7 Windows XP mode? I am running Win 7 Ultimate 64 bit edition.

This is the dialog box:

Update: the computer is an HP TouchSmart, with American Megatrends BIOS v02.61. I looked into the BIOS set up but it is quite simple and dosen't have something for "hardware assisted virtualization". The CPU is Intel Core 2 Duo T5750.
