Won't launch... again

[ELaw 11]

I have the MS Store version of MSFS.  Went into the Store yesterday, it said there was an update for FS, and I downloaded it... it was just about 1 gigabyte.  Double-click the FS icon to launch it, and I get a UAC prompt ("Do you want to let this app make changes to your device?").  I click "yes" and get the same prompt again.  Click "yes" again, the prompt goes away and I get a red error window that says "This app can't open.  Check the MS store for more info...".  When I go into the Store and hit "Get updates", none are found.  MS flight simulator version shows as 1.12.13.0.

Last time this happened I had to uninstall and reinstall the whole program.  Am I going to have to do that again?  If it matters, my "community" folder is empty.  Not that I don't enjoy repeatedly reinstalling this program, but I'd much rather use it. 😕

Just to "close the loop" on this, I submitted a request to support and they got back to me very quickly.  This is what they said:

Here are the first things to do when the Microsoft Store app is not working as usual:
 

1. Sign out and sign back in the Microsoft Store app

·         Open the Microsoft Store app on your computer

·         In the Windows Search Bar, type "Store"

·         Click on Microsoft Store and select "Open" in the menu

·         Click on the icon in the top right-hand side corner of the screen

·         Under your email address, click on Sign Out

·         Reboot the computer

·         Open the Store and click on the profile icon again, then select "Sign in" and enter your credentials

·         Make sure to sign back in the Microsoft Store with the Microsoft account used to purchase Microsoft Flight Simulator

2. Reset the Microsoft Store Cache.

·         On your keyboard, press the “Win Logo” + “R” keys

·         Type: WSReset.exe and press “Enter”

·         A black window will pop up

·         Wait until the pop up disappears and the Store comes up

·         Reboot your computer

 

I followed the procedure, launched FS and... it's now downloading 14 gigs of update!  It appears the problem is solved.

Thanks for sharing. This procedure can be used as a first step to try and fix a few other things like in-sim marketplace purchase issues as well.

The same thing happened to me. Today I tried to open MSFS and the icon is totally blank and it won't launch! Why is this happening?
