So I just upgraded from version 3 to 4. That is, I purchased version 4, and tried to install it, but got rather stuck. It says that I need to shut down Windows XP, except that Windows XP is not open, and I have already uninstalled version 3. what to do? I am not quite computer savvy and really need Parallels for schoolwork.
Thanks for any help you can give
