I currently use TrueImage 8.0 on my XP system. I'm going to be replacing my system with one that runs Vista. I understand I need to upgrade my version to at least 10.0, and that's not a problem. My question is this: I understand from these forums that 8.0 won't even install on Vista. Now, if I purchase an 11.0 upgrade, instead of a full installation, does that mean I'd normally have to install 8.0 first, then 11.0 over that, or does the 11.0 "upgrade" actually install clean? If the former, obviously buying the upgrade version would do me no good. Help? Thanks much in advance!
