Personally I have developed programs on 2K that would not run on 97. I only
imagine there are similar problems among other version changes. The only
solution I've found is to do the development in the oldest version you expect
to be used. The compatibility in that direction seems to be ok. At least,
now I do all my development in 97 and I have no complaints from 2K or XP
users............

I am going to start a program that will be used on multiple computers. Some
have EXCEL 2003 and some have 2000. My development machine has 2003.

If I supply the interop DLL from my computer to the machines running 2000
will my program be compatible? if not what is the best way to go about
starting this project?
