Error 429 - Active X (Can't create reference to RDO)

I am supporting a vb5 app that is working fine on a few machines.  We just had to update one executable and we are getting the following error even when we compile the unchanged code as is:

Error 429 - Active X cant create object

It happens when using RDO references as follows (for debugging):



Private Sub Command1_Click()
    Dim mEng As RDO.rdoEngine
    Dim mEnv As RDO.rdoEnvironment
   
    On Error GoTo ErrHnd
   
    Set mEng = GetObject("C:\winnt\system32\msrdo20.dll", "RDO.rdoEngine")
    'Set mEnv = RDO.rdoEnvironments(0)
   
    MsgBox "Success"
Exit Sub
ErrHnd:
    MsgBox "Failed"
End Sub


We have tried a few things with this... any ideas... we have reregistered the specific dll and even tried using the exact version and registering from other envionments that work.  ONly the old exe works.
