How Can I Verify if the Add-in Has Been Loaded?

You can use the following VBA code to verify if the add-in is available (loaded). You can show a warning (at startup or when clicking a button) if the add-in is missing.

Public Function IsTBarCodeWordAddInActive() As Boolean
Dim objAddIn As COMAddIn
IsTBarCodeWordAddInActive = False
For Each objAddIn In Word.Application.COMAddIns
  If objAddIn.ProgID = "TECIT.TBarCode.WordAddIn" And InStr(objAddIn.Description, "11") Then
    If objAddIn.Connect = True Then
      IsTBarCodeWordAddInActive = True
    End If
  End If
Next
End Function

How to check if available:

If IsTBarCodeWordAddInActive() Then
  MsgBox "All OK :-)"
Else
  MsgBox "TBarCode Word Add-In (V11) is missing!"
End If
