Windows 10: “This app can’t open” Fix

Windows 10: “This app can’t open” Fix

July 19, 2018 by Mitch Bartlett 1 Comment

You may have a problem opening metro apps like Edge, Calculator, or Calendar in Microsoft Windows 10. A message that says “This app can’t open. (App name) can’t open while User Account Control is turned off.”

A similar error message that may appear is “This app can’t be activated when UAC is disabled.”

You can solve this problem with these steps:

Fix 1 – Enable UAC

  1. Select the “Turn on User Account Control” link on the message that appears, or go to “Control Panel” > “System and Security” > “Security and Maintenance” > “Change User Account Control settings“.
  2. Slide the slider to any of the top 3 selections.

  3. Restart your computer.

Fix 2 – Reset Windows Store

  1. Select “Start“, then type “powershell“.
  2. Right-click on the “Windows Powershell” selection, then choose “Run as Administrator“.
  3. Type the following command, then press “Enter“:
    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Fix 3 – Use Troubleshooter

  1. Select “Start“, then type “troubleshooting“.
  2. Select “Troubleshooting” > “View All“.
  3. Choose “Windows Store Apps“.
  4. Select the “Advanced” link.
  5. Check the “Apply repairs automatically” box and then select “Next“.
  6. Follow the on-screen instructions to complete the troubleshooting process

FAQ

Why do I have this problem repeatedly even after I change the UAC setting?

The UAC setting may revert because of a Group Policy that is enabled on your computer. If you are in an enterprise environment, contact your IT department or System Admin.

Is there any way to run Metro apps with UAC disabled?

Nope.

    God d*mn anoying warning box ! MS OS is gettin more & more stupid & stupidity integrated one !!! Nothing helps ! It seems that if MS OS isnt set-up-ed MS way (all crapp and bloatware running and enabled then it will be operate with maulfunction ! Crap ! Full blown win10 isnt performanse one way too many services running ! Poor performance/distraction with bloatware integrated not to mention privacy issues ! Services should run only when needed and then stop and not running all the time! Win 10 Administrator account is very limited and thus i have such issues with it. Microsoft Moorons enforce OS their way and we users dont like it. OS is uselles to me if i can not controll it (ms has wasted that trust long time ago and still does) !
    It’s the modern mistery how such pece of crap OS can exist and MS not going broke ????
    Going back to Win7 at least there i have some control over it (can enforce settings user way at least cos ms doesnt repect user setting, they overwrite it every god damn update time 2x the year). Ms should go broke – why are users payig licenses for such non controlable crap OS ???
    And u cant turn updates of in win10 ? The only way MS doesnt screw your setting up is running it completely offline if one doesnt have choice and must run/use it !!!

Did this help? Let us know!
