I have been using Mathematica 9 available as a shared application from the university where I teach. I installed a trial version of Mathematica 10, decided it was not worth the money, and uninstalled it when the trial ran out. I have since discovered that the uninstaller does not do a thorough job of cleaning the registry and has left behind some code that sporadically tells me my license has expired when I run Mathematica 9. I can clean the registry manually if I have to although it's a pain. Will this get rid of the offending code also?
