need to have users share add-ins
 

I have a problem with an application I created.
The users are running office 2000 or office XP pro.
We have a need for specialized functions I created to be shared among several users. The problem is that some of us have laptops, others have desktops.

I keep a copy on the network to share, and the laptops have a local version.
However, whenever someone goes into the sheet, they need to refresh the links from the editlinks menu to get the functions to work.

Is there a way to share an add-in amongst us?
Ideally, excel would look for the version on the network, and if not found, use the one local on their hard disk.
