Successfully upgraded to Parallels 13, windows10 and Publisher 2016 a few weeks ago. All worked fine. Attempted to do some cleanup on the Mac this week and one of the suggestions was to uninstall unneeded plugins. It found one (cant remember exact) but basically was to be able to open internet explorer. Since I do not use IE I didn't think it would be a problem to uninstall the plug in. Uninstalled it the other day and tried to go into parallels today and it wont open. do I need to uninstall everything and start over or is there a plugin i can reinstall? I know I should not mess with things I know nothing about. Thanks in advance. Nancy
