Hello I have a vista business sp2 that worked perfectly with parallels v3. I upgraded to parallels v5 yesterday and the virtual machine was upgraded correctly. But now I have a message : "This copy of Windows is not activated. Click here to activate windows now". So I click, and have the message "Reinstall windows : windows must be reinstalled to activate, insert the windows installation dvd or cd into your computer to begin the reinstallation process." Is there any way to avoid reinstalling from CD... this cd is rather old and I'll have to re-install all upgrades and all softwares, it will take me days to do this... Thanks a lot
