With the help from this forum, I successfully installed VMP (VMware Player) along with XP Mode on two Dell XPS 8000 and Optiplex 360 computeres. Both computers run 64-bit Windows 7 Professional, So far, Win XP programs run any problem on both computers. But I noticed an error box on the screen when VMP runs on Optiplex 360 (see the attachment):
"Software virtualization is incompatible with long mode on this platform. Disablilng long mode. Without long mode support, the virtual machine will not be able to run 64 bit code. etc."
Since XP Mode only runs on 32-bit, I thought that 64-bit does not matter with running XP mode or VMP. Could someone explain more in plain language what this error message affects on running VMP? Note: when I checked BIOS of OptiPlex 360 (purchased in 2010), virtualization was not listed in the BIOS meun.
