Upgrade 3.0 to 4.0 -will I have to reinstall windows?

[GadgetNeil]

Hi,
If I upgrade to 4.0, will I have to reinstall windows, and will I have to then reinstall all the software I currently have loaded in Parallels 3.0?

I didn't have to do any of that -- just installed the Parallels upgrade and continued where I'd left off.
