Broken after Windows upgrade

Broken after Windows upgrade

I upgraded to 8.5 on Windows, and the service failed to start.  I was able to start the app from the shortcut.  I uninstalled the update, and now I can't even start the updatemanager to reinstall the update.  Can I reinstall the entire 8.5 and have it recognize my license, or do I need to start reinstalling from my old version and add all the patches again?
