I have been developing an Excel AddIn project on a Vista machine with Office
2007. When the AddIn workbook is opened it calls a function that adds a
custom menu to the workbook that uses the AddIn. Works fine on Vista but
when I move the AddIn and workbook that uses it to an XP machine it won't
compile, complaining about not being able to find CommandBarPopup object or
library. If it's important, I put the AddIn in the same directory as the
Worksheet that uses it.

So, how can I fix it so I can esily install the whole thing on either Vista
or XP?

TIA
