Did you try using the Norton Remove and Reinstall Tool?  These are often far less "complicated" and, as a result, more accessible since they are very purpose driven.  You're generally asked which you're trying to do and that's that.  I don't have Norton and haven't used this, but I've used plenty of software in this class.
