My Windows 10 calculator stopped working. I can't seem to re-install it using the PowerShell methods described on various Google searches. I receive 'Package could not be registered' errors.

Here's what I have been getting:

PS C:\Users\Paul> Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1601.49020.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered.

Is there some way to remove the calculator app from the registry to I can re-load it through the Microsoft Store?

  • You need to format your question better, its nearly impossible , to tell where the command starts/ends and where the error message begins. If you run get-appxpackage -allusers | Select Name, PackageFullName Is WindowsCalculator shown in the list? – Ramhound Jun 24 '16 at 18:18
  • Have you verified other UWP work, it seems odd, only the calculator would stop working. Windows Store – Ramhound Jun 24 '16 at 18:19
  • Yes, WindowsCalculator is in the list from the get-appxpackage command. It is also in my start menu. When I click it, the circle spins for a while and nothing happens. Other UWP programs are working ok. Groove music, Weather, etc. – Paul B Jun 25 '16 at 0:48
