Stuart,

Actually is stopping the execution of the code if either of the two files
"abc.exe" or "xyz.dll" are not present in the application directory path.

Thanks to you both.......looking for the file was my guess.
I assume that Application.Path MUST exist and be valid
since it must represent the host application (ie Excel or,
say Office) under which the sub is running.

I have 'found' these lines:

If Len(Dir(Application.Path & "\" & "abc.exe")) = 0 _
Or Len(Dir(Application.Path & "\" & "xyz.dll")) _
= 0 Then
MsgBox " very long message "
Exit Sub
End If
Load UserForm1
UserForm1.Show
End Sub

What exactly is the If statement trying to determine,
please?

Regards.
