I installed Parallels and Windows XP Pro VM with no problem under the Administrator. I had set up a user for others to use the Mac in a church setting, but when I tried to run Parallels from that user it had no OS available. My question is, is there a way to make the Admin. VM available to the user? I have used up all my Windows authorization to install. Besides, isn't that the same as putting the OS on two different machines? Any help would be appreciated.
