Hi
I have many workbooks on a school system that make reference to a common
Addin for the macros required. Sometimes when a workbook is loaded for
the first time, it does not know where the reference Addin workbook is
located. This generates the following error:
Compile error:
Can't find project or library

- and also places the unsuspecting user in the VBE mode.

How can I trap this event ?

Thanks in advance

Hi Andrew,

A simple way would be to have a dummy function in the add-in, and make a
call to it early in your code. You can determine there whether the add-in is
loaded or not

Dim myVal
On Error GoTo no_addin
myVal = Application.Run("myAddin.xla!myFunc")
Exit Sub

no_addin:
MsgBox "Add-in not installed"
