I have an add-in that on one user's PC is saying office library invalid or
contains invalid references when it is executed. However, in Tools,
References, all is fine. None are missing. All references are the same as
another add-in which works fine. I've rebuild the add-in with the code
cleaner and the max number of lines is 509, and the add-in is quite small.

The user is using Excel 2007, but it works on other 2007 machines.

Any thoughts?
