I had a Workbook_AddinInstall method so I could go back and forth
between developing in an Excel Workbook and then later saving my work
as an AddIn.

Workbook_AddinInstall wasn't needed to actually install the AddIn.

I forget what others had to set their security at.

Hi
Is the Workbook_AddinInstall() called by the Workbook_Open sub? Also,
what is the macro security level set at on the other PC (you need to
click on "Trust Access to Visual Basic Project" in the trusted
Publishers tab in macro security)
