I am sorry to report that no matter what I do, I cannot get Flight Simulator to work even with the ISO file on a high end Dell Alienware machine. The process gets halted with in a processing loop and there is no disc access going on.
I am having same repeated failure having restarted, reinstalled software, firewalls up or down, and the funny thin is it runs perfectly on an older intel chipset in my desktop - with the same OS, the same version of bit defender, configured the same, and on the same network with all of the same OS patches...
I think I am going to take a rest for a while and wait for the next major update.
I am pleased the game is working for some of you and happy landings my friends.
