Dave it would probably be a good idea to have a word with Aerosoft and get them to make the new installer available in their updates section of the Aerosoft website like they do for ever other product they sell. Old customers currently cannot download the new installer from Aerosoft, I've just tried adding the product that I purchased from FSPilotShop to the registered product area at Aerosoft, it registered fine with the Aerosoft installer key that was supplied by FSPilotShop, but when going to the actual product update support page for PFE it is just a page of questions and answers, there are no updates at all like there are for all the other products that Aerosoft sell. In one of the questions in the FAQ they are actually telling customers to come to the Oncourse website to get updates
Anyone can register PFE at the Aerosoft website and get updates even if they didn't actually buy PFE directly from them, that's one of the great things about products that are sold through the Aerosoft installer, its just a shame that they haven't currently got the PFE updated installer listed in their updates page yet.
