I have been using 3.X and tonight it said there was an update. So I downloaded it and when Windows re-started, it installed the new version of parallels tools. Once that happened, Parallels would no longer work correctly. It would not boot the virtual machine-it said something like a driver was missing try again or reinstall parallels. I have a bootcamp partition. So I uninstalled parallels desktop, but when I boot to windows in bootcamp, I can not uninstall the parallels tools. Windows says I must be running the virtual machine to uninstall. Any suggestions?
