Computer erroneously trying to install Office

When I turn on my computer, I get the following messages in sequence, as
I cancel one after the other:
A. Plse wait while Windows configures Microsoft Office 2000 Professional.
B. The feature you are trying to use is on a CD-ROM that is not available.
Insert....etc.
C. The path Microsoft Office 2000 Professional cannot be found....etc.
D. An error has occurred in script on this page. Line 79....etc.
I am not trying to install this - does anyone know how to solve this?
Thank you!
