Hi, in the following code, I get the error "Automation Error" when the execution reaches the line Set objInterface...

Code:
Private Sub Command1_Click()
    Dim objInterface As Object
    Dim objServer As Object
    
    On Error GoTo cuError
    
    Set objInterface = CreateObject("Intrf.Interface_Server")
    Set objServer = objInterface.objGetClassInstance("Class1")
    MsgBox objServer.showWindow
    
    Set objInterface = Nothing
    Set objServer = Nothing
    On Error GoTo 0
    Exit Sub
    
cuError:
    MsgBox Err.Description
    Set objInterface = Nothing
    Set objServer = Nothing
    Exit Sub
End Sub
Object Intrf is installed on a server on the network. What are possible reasons for that error?

Thanks in advance
