How about just setting a reference to morefunc in your workbook's project.

Inside the VBE (with both workbooks open and your workbook's project active)
tools|references
check the project associated with MoreFunc

Each time your workbook opens, the addin will also open.

Hello
I have created a file that uses Longre's morefunc. I have the .xll
located in the same directory as the file. How do I check that my
user's also have the add-in enables and if not, enable it for them?
Thanks!
Steve
