I bought MSFS Premium Deluxe from the MS Store during the early purchase period. Before then I was flying Prepar3d v5.1. I have been flying the Microsoft Sims since MS95. I've been building my own Sim rigs since 1997. My system now: AMD 2700, 32GB ram, 2070GPU. WIN 10 20H1. Not top of the line, but no slouch. ALL apps and Windows kept up to date. Few problems with MSFS, even when others have had problems. However, like the OP. this last update to SU5, which I attempted after Windows update 07/27/21, I couldn't even load the Sim. Which had worked flawlessly before the WIN updated. It would just go to the Store. Period. now, the Store won't even update. So, those who are not having problems, great, but don't say just because you aren't, don't assume others aren't.
