Cannot identify the object "HPE MyFlight Sample Applicatio" (of class Window).
Verify that this object's properties match an object currently displayed in your application.

Line (1): "Window("HPE MyFlight Sample Applicatio").Activate".

Tip: If the objects in your application have changed, the Maintenance Run Mode can
help you identify and update your steps and/or the objects in your repository.
