We use Windows 7 for testing at work. When installing it under the latest Parallels, entering the MAK (activation key) did not work correctly pre-boot. When going to try this within windows, it complained that there was no valid DNS name -- well of course there isn't, I'm running inside a virtual machine, behind a NAT access point, behind a cable modem! LOL Anyway, I wonder if anyone else has had this problem. I know the code we have is valid, I install this a lot. Thanks!
