Ok, so to begin my problems I did a system restore because of a bad driver package that made my keyboard stop working (that has been fixed by the sys restore). That being said I know this is the cause of my problem because it has happened before (previvious system restores) but, what is different about this particular time is that I can't uninstall my program (Autodesk Revit 2011). Which brings me to my question, is there a way to make my computer think that this program has been uninstalled via deleting reg keys or some method?
