Hi, seems that activation is being tricky here. I have a freshly installed (licensed) Parallels on my Mac and a licensed XP express image but after entering the password, XP wants to activate the MS license. If I say NO, it boots again. If I say YES, it says already activated and reboots after clicking OK. So two choices but the same effect ;-) Your help, John, is greatly appreciated.
Same problem The windows keep re looping to activation then reboots. FYI I'm using my old laptop's hard drive with windows on it. And using a USB port to run the hard drive from my MAC....
