Windows 10: “This app can’t open” Fix

Windows 10: “This app can’t open” Fix

By Mitch Bartlett Leave a 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.
