*HELP* I am getting "this app can't open" after SU7 was made on MSFS2020

Hi Ziv. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

See if you can System Restore to a point before the problem began following this guide: https://www.windowscentral.com/how-use-system-r...

System Restore is your first line of defense and can take you back to a point before a problem began like a time machine. If it doesn't help then you can undo it. Read about it first in the tutorial above and then try restoring to just before this started.



Then try these fixes for SU7 update on MSFS2020:

For further help I'd post in MSFS forums above to speak directly with enthusiasts.

I hope it helps.

Dear Greg,

Thanks for your prompt reply, I apreciate it.

I tried few of your fix offers.

Eventually I uninstalled the entire simulator, and re-installed it again from the XBOX app, and not the MSstore.

This time it workedn and the sim is back working again...

So far so good.

Thanks for your help!

Best regards,

Ziv

I had the same problem. It worked after I started MSFS with XBOX app and when I got the error switched back to XBOX app, logged out, not closed, and switched back to MSFS and tried again.

SOLVED - Great work around. Thanks for the help, this fixed my problem. For those still trying to understand once I received the error I tabbed over to the Xbox app, signed out, left it open and then went back to the open MSFS2020 and tried it again. It then
asked me to sign into Xbox App again and after that VOILA! it worked.

Ok after the last few updates with msfs2020 steam version I've had virus issues on my PC also on my Xbox msfs2020 I've noticed that the F-18 that I can't turn the position lights on and strobe lights on so I can't fly at night and when I go to turn them brighter the knobs are already at 100 percent but can't see anything no lights just taxi light works

Hi!

I've the MSFS2020. In the marketplace it is possible to click BUY for a product. But after this I become the error "buying not possible".

The accounts in the MS Store, XBOX-App and MSFS2020 are the same.

My creditcard is working - because I bought a product today in the MS-Store.

Anybody any idea what there is wrong?

Thanky.

Mark

So i have that issue every couple weeks. I just log off msfs2020 and log back in and it works every time!
