Apologies if this is a dumb or already asked and answered question but.... I'm finally going to bite the bullet and switch to a Mac (as soon as they announce the new iMac upgrades ) after many frustrating years as a Windows user. However, I do have a few applications that will require getting VirtualPC (yes, they are necessary programs that don't have Mac versions). My question is about licenses. If I already have a license for my existing purchased version of W2K, can I just transfer that license? What about older versions of windows ? Would I need separate versions of VPC?
