I know that I can invoke administrative privileges like that, unfortunately, unlike Unix, not everything works when you invoke them that way. For that matter, many installations initially fail due to a lack of registry write privileges even when I am logged in as administrator. It is so weird because it will let me go into the registration editor and give myself write privileges over certain keys and branches of the registration database but it won't let the installation program I invoke from the administrative account just create the keys that it needs. Power is dangerous and you have to be careful, but power that only works intermittantly is even more dangerous because it creates a dangerous and frustrated administrator.
