Hello, I need to upgrade from Parallels 5 to 7 but I'm wondering a few things: Do I have to reinstall my version of Windows and start from scratch with the Parallels install? I have third party software (not virus-related) installed in Windows that I can no longer obtain with ease. Will these programs need to be re-installed? Basically, will my Windows install have to be started all over again or....? Sorry that these are newbie questions - I'm totally new to doing this on my own.
