Thank you for the reply
The other OS in mac osx, the laptop is a macbook pro.
I orignally installed it on the partition so it was dual boot and registered it. then i started it up in pararelles (vm software for mac osx) and it said it need to be registered, but i didn;t do it as i didn't know if it would fail.
After using it for a day or two in the VM software with out registering it, i went back to the physical version and it said it was already registered. Do you think if i register the windows copy within the vm then the physical verision would become un-registered?
