Flight simulator.exe cannot start or run due to incompatibility with 64 bit versions of windows

I’m getting the same thing flight simulator 2024 runs fine It just creates that pop up upon launch.
I’m on Windows 11 24 H2 and MSFS 2024 has the most recent update

About a month ago my XBox app miraculously came to life and so did Flight Simulator. This was great until yesterday. The latest update refused a couple of drivers as vulnerable. They were iqvw64e.sys and iomap64.sys. I think these drivers are required for XBox because as of that update my Xbox app is not working and neither is Flight Simulator. So I guess I have to wait for another miracle. I don’t have any idea why it started working. I was in the habit of just giving it a try every other day or so and one day it started. WOW.

Had the same problem after a Windows 11 update, after trying Lots of things without succes.
I logged out of the Xbox app and the Store and rebooted my PC. After the reboot i logged back in the store and then the Xbox app FS2020 was fine again. Hope this will help.

No, that’s too simple. My Microsoft Store turns on but I cannot download or update any apps, especially XBox and Flight Simulator. The MS Store has not worked correctly on my PC for over a year. I am not the only one with this problem and there appears to be no solution. Except to buy a new PC. Even a clean reinstall of Windows 11 did not fix it.

I have a possible solution for this problem. I was able to get the Flight Simulator to start up and run as it should. Here is what I did. I opened the Nvidia Experience app. Went to The Graphics Section, then down to Microsoft Flight Simulator. The first thing under Microsoft Flight Simulator is Driver Settings, click on RESTORE. I did it twice for good measure. Then I went up to the the verticle dots and clicked on that, then clicked on PLAY. Then sim started after about 15 seconds. I hope this works for you and also for me the next time mine stops working.
