First thing to do is determine whether you really need that reference.
Go into the VB Editor and check the References dialog. You should see
MISSING: beside one of the selected references at the top of the list.
Uncheck it, then do a compile on your application. If it compiles cleanly,
you didn't actually require the reference, and your problem should be
solved.
If it doesn't compile cleanly, that still doesn't necessarily mean you need
the reference: your compilation problem could be due to something else. If,
however, you determine that you really need that reference, you need to
determine whether it's legal for you to copy it to your laptop. (It's not
part of Microsoft Office)
