Hi - I'm using an AddIn which when added creates a menu. The same
workbook when opened via C#/interop shows that that the AddIn is
present and installed but the menu is not there.

I'm not an Excel expert - is this surprising behaviour in an AddIn ?
The same user runs Excel ' manually' as runs the .EXE which automates
Excel - I don't understand why their experience is different.

Could anyone suggest a means to make the menu visible ?

thanks

Richard.
