With respect to my answer above you might also find this useful to check whether the macro exists

'=================================================================================
'- CHECK IF A MODULE & SUBROUTINE EXISTS
'- VBA constant : vbext_pk_Proc = All procedures other than property procedures.
'- An error is generated if the Module or Sub() does not exist - so we trap them.

    Dim MyModule As Object
    Dim MyModuleName As String
    Dim MySub As String
    Dim MyLine As Long
    '---------------------------------------------------------------------------
    '- test data
    MyModuleName = "TestModule"
    MySub = "Number2"
    '----------------------------------------------------------------------------
    On Error Resume Next
    '- MODULE
    Set MyModule = ActiveWorkbook.VBProject.vbComponents(MyModuleName).CodeModule
    If Err.Number <> 0 Then
    MsgBox ("Module : " & MyModuleName & vbCr & "does not exist.")
    Exit Sub
    End If
    '-----------------------------------------------------------------------------
    '- SUBROUTINE
    '- find first line of subroutine (or error)
    MyLine = MyModule.ProcStartLine(MySub, vbext_pk_Proc)
    If Err.Number <> 0 Then
    MsgBox ("Module exists      : " & MyModuleName & vbCr _
           & "Sub " & MySub & "( )  : does not exist.")
    Else
    MsgBox ("Module : " & MyModuleName & vbCr _
        & "Subroutine   : " & MySub & vbCr _
        & "Line Number : " & MyLine)
    End If
End Sub
