When I try to run one of the Windows 10 pre-installed Store apps, or indeed the Store app itself, I get the following error message and the application won't run:

Activation of application Microsoft.WindowsStore_8wekyb3d8bbwe!App failed with error:

{Application Error} The application was unable to start correctly (0x%lx). Click OK to close the application.

Other error messages which show up in the Event Viewer are:

under AppModel-Runtime:

0x23F: Cannot create the process for package Microsoft.WindowsStore_11602.1.26.0_x64__8wekyb3d8bbwe because an error was encountered while performing the integrity check. {Application Error}

The application was unable to start correctly (0x%lx). Click OK to close the application.

and under DistributedCOM:

Unable to start a DCOM Server: App as Unavailable/Unavailable. The error:
"575"
Happened while starting this command:
"C:\Program Files\WindowsApps\Microsoft.WindowsStore_11602.1.26.0_x64__8wekyb3d8bbwe\WinStore.Mobile.exe" -ServerName:App.AppXqagq4n4gvy0tjw576pgh6xr601s1h1mv.mca

Standard applications work fine, only Store apps are affected. I cannot think of any changes I've done to the system lately that could have affected it. I've made sure I've got all Windows updates installed.

  • Do you have UAC enabled?

  • @Ramhound Yes, but I've just disabled it for a test and it didn't help.

MS released a tool that's supposed to help fix windows 10 store issues, you could try run it and see here's the address: https://solutions.diagnostics.support.microsoft.com/run/6b089dc3-50d6-4add-9959-337fca72c533#

  • Well, it definitely did something. Now rather than get an error, I can see the frame of the window of the app for a fraction of a second before it crashes without a message. Oh, and my desktop wallpaper's gone, for some reason.

  • I forgot to say it errored with the same error message 'The application was unable to start correctly'.

I had a similar error (though "2147942402", which is "File not found") when trying to run several Microsoft Store C:\Program Files\WindowsApps applications.

  • Maybe coincidentally, but the issue was resolved after running: Component Services comexp.msc
  • There expand Console Root->Component Services->Computers->My Computer
  • Right-click My Computer
  • Properties
  • Default Properties tab
  • You will probably see the option Enable Distributed COM on this computer enabled. Uncheck it (temporarily)
  • Apply
  • If you see a warning message confirm with Yes
  • OK
  • Open Properties and re-enable the just disabled option

This as it seems shouldn't change anything, but possibly some other settings get reset with disabling and re-enabling and so the applications started to work for me again.
