Hi Bernie and thanks.

That is the line where the error occurs, however your suggestion still fails
to prevent a subscript error if a "False" reply is generated...

Any other suggestions?

Is the error on the line

If AddIns(argName).Installed = True Then

If so, then try:

If cBool(AddIns(argName).Installed) = True Then

In Office 2007, I'm using the following function to determine whether an
Add-in is installed, but if the answer is "False", rather than false, I get
"Subscript out of range" error. Any idea what I'm doing wrong? How can I get
this to run right?

Private Function AddInInstalled(argName As String) As Boolean
'return true if an addin is installed:
If AddIns(argName).Installed = True Then
AddInInstalled = True
Else
AddInInstalled = False
End If
End Function

Thanks in advance...
