In my old stock of software I have found an unused CD of M/S Office that came with another computer; I have installed it on my Toshiba laptop. When I try to use it I am informed that I need Administror permission. Not being an expert I have tried all sorts of things to be able to use this copy of Office. As far as I know I am the Administrator and use a password to log in. How can I get rid of the "Administrator" to enable my use of this software?
