<BBackground Information<B: I am a consulting Network Admin for a CPA
firm. Prior to my arrival as an employee, all network, computer workstations
and software were installed on computers when purchased and user/workstation
information was NOT recorded on each copy of Microsoft Office.

One user was having an error opening an Excel Worksheet from a shortcut on
the desktop. Each time it asked for a Registration Key. Because there
wasn't one with her specific name on it, I entered one and now I get an error
saying the Registration Key is incorrect and the application will now
terminate.

How can I go in and change the registration key? I have licensed copies for
every single machine in the office, I am going to have to try them all.
