Thanks for trying to help, though either I don't understand what you're trying to say, or it looks like it's not helping at all.
If I install under XP mode, then that software only runs on the virtual machine, even though I can launch it from windows 7, hence it won't protect my windows 7 OS based machine.
I know that I would have to install the AV software in XP mode even if it is already installed in windows 7.
The money question is, how do I install it twice (once in 7 and once in XP) without having to pay for 2 licenses.
