I found a reasonable workaround.

I moved the file DATA1.MSI from the CD to the Office 2000 folder and browsed
to it when Word 2000 wanted the Office 2000 CD. Word goes through it's
installation silliness and then starts. This occurs every time I run Word
2000 after running Word 97, but it's nowhere near the hassle of having to
insert the CD when I want to run Word 2000.

Thanks for your help,
David
