Dissy's fix worked for me. Thank you Dissy. Had to do it 3 times though. So 40 hours after first starting to download I got to fly. Took some screens of Perth Western Australia where I Live and a mate who's an ATC in Melbourne and a pilot who learnt to fly here asked me who I was joy flying with!!! :) Impressive... But it's a big shame that they have muffed up the install process for so many people. I could of had it for "free" with Game Pass but bought the Premium Deluxe and was on the verge of seeking a refund as I was very annoyed.
