No need, you can remove faulty/duplicate entries with CCleaner, or this; click here which will make backups of removed items. When I say "remove", I mean removing the duplicate reference to the file/program, not uninstalling the program. If you accidentally delete both entries and somehow lose the backups made by the program above, reinstall that program in the conventional way to restore its Add/Remove entry.
Having said all that there may be something else wrong with your system that caused the issue in the first place.
