Hello Dave, your approach brought me another idea. What about if I would always have two "launching" standalones one behind the other. First one only to check and do the updates, calling the second standalone and quitting. The second standalone is nothing else, as a carrier of the standalone engine, splash screen and what else wanted and calls the main stack. If this works I could always update the newest engine with the second standalone and the only thing what I can't do with this approach is to update the first standalone. Assuming that I don't want to change anything in the update procedure, this would be the easiest way. Am I sure that this way, my main stack will be handled by the engine of the second standalone, or would it still be handled by the engine of the first standalone? Thank you Tiemo
