I tried to use the XP mode in a new installation Windows 7 Pro VM. Having installed both Virtual PC and XP Mode the XP Mode First Run Setup fails right at the very end. Running the Hardware Assisted Virtualization (HAV) detector tools states that the PC does not have HAV. THe Hofix installer says that the hot fix does not apply to this PC. Is it not possible to run XP mode on a Windows 7 VM?
