Exporting contacts in Office 2000

I have a client that can’t find any of the software that came with her Sony Vaio laptop. She is running Office 2000 premiere. When trying to export her contacts – it states that must be installed. I tried to use my office 2000 Professional CD – but of course that wasn’t compatible. Any suggestions on how I can export these to her new PC?? She is running Windows 2000 Professional.
