Notes OLE Automation - Get error ActiveX component can't create object

I have developed a VB application that uses OLE Automation to do several Lotus Notes archiving activities. It runs fine on our developments PCs. When running it on Client PC, option dialogue window appears fine, when we come to create a Notes.NotesSession object, it produces error ‘ActiveX Component can’t create object’.

The VB application is using OLE Automation to perform several archiving activities, some of these activities

use Notes Front end classes (e.g. Open NotesUIDocument and NotesUIWorkSpace).

The Client PCs are imaged, We have no control over the image (i.e. we cannot reinstall Notes). Client PCs have

Lotus Notes Client (Version 6.0.1) installed, NO Designer or Admin Clients.

The code snipnet (VB 6) is as follows:

Public Session As Object

Public ws As Object

Public custDb As Object

Public TransferOptions As Integer

Public DatabaseName As String

function ExportMessage(dbName$)

Dim serverName$, DbReplicaID$, lookupViewName$, DbPathName$

Dim db As Object, parentDoc As Object



On Error GoTo HandleExportOpenMessageErr



DatabaseName = dbName$

serverName = GetServerName(dbName$)  ' this returns Server preferred by user

DbPathName = GetPathName(dbName$)    ' this returns full Db pathname

    

Set Session = CreateObject("Notes.NotesSession")

Set ws = CreateObject("Notes.NotesUIWorkspace")



Set custDb = Session.GETDATABASE(serverName, DbPathName, False)

If custDb Is Nothing Then

    MsgBox "Unable to Open database " & DbPathName & " - On Server " & serverName &  Chr$(13) & _

    "Check that the Server Name and Db Path are correctly specified in Setup Server Path Option"

    Exit Function

End If

End Fuction

Comparing the registry of the Client Pc and our Development Pc. The Client PC has no entries for the following classes.

CLSID class {29131401-2EED-1069-BF5D-00DD011186B7} and {29131502-2EED-1069-BF5D-00DD011186B7} are missing from the Client PC.

Any idea why these are missing.

I have recreated these entries on the Client PC using .reg file, now the REgistry entries are identical. I still get the same error.

I have tried registering nlsxbe.dll via regsvr32 nlsxbe.dll

Any idea what the problem is and how I can overcome it. Thanks in advance.
