Connecting to a Com interface with two VBScripts

I am trying to connect to an application that exposes a COM interface. My VbScript Code looks like this: 

  Set App = CreateObject( "Starter.Application")
  Set Measurement = App.Measurement
  WScript.ConnectObject App, "App_"

  If Measurement.Running Then
      Measurement.Stop
  End If

This allows me to Control variables within the Starter-Application.

What I want to do now is connect another application to the same COM interface, to influence other variables within the application. Naturally, when I start the application using the CreateObject command, I get a new instance of the application.

How can I connect to the same instance that was already created with another script?

    A: Make your COM server an "out of process" .exe:

    NOTE:

    If your COM/ActiveX application is already out of process - but doesn't "share" state like you need, you can create your own VB6 out of process exe to "wrap" the original application.
