"There’s a problem with Cortana. Reinstall the application from its original install location or contact your administrator."

I have a similar problem.

At some point calculator stopped working, then Windows search and the netflix app, for example. all of these app open, then immediately crash-close.

Basically, the problem was Cortana. After lots of following online instructions like one of these pages, I managed to remove Cortana for the current user on this Windows 10 PC. Now I have the problem though that it won't re-install, not via Microsoft Store (the "get" button is simply not present), nor via Windows PowerShell (incl. administrator rights). When I type in either of these (and press enter afterwards):

• Get-AppxPackage -AllUsers Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• Get-AppxPackage -name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Windows PowerShell does nothing, ignores the command. I cannot see any "Deployment blabla" layover, not even for a second. (I do see this, if I try to re-register/re-install another app). Thus, rebooting the computer after that has no effect.

Cortana and Windows Search works on other users on the same PC, and I have no fu***ing clue on how to force re-installation of Cortana for this or all users of this computer. Reinstalling the computer is not an option, so please: don't suggest it.

Hello, thank you for being patient with me.

I did all the steps in your reply, however when I paste "Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}" it causes an error.

The error reads: Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF3, Package failed updates, dependency or conflictvalidation.error 0x0: Reading manifest from location: Microsoft.WindowsStore_22204.1401.5.0_x64__8wekyb3d8bbwe.xml failed witherror: The operation completed successfully..NOTE: For additional information, look for [ActivityId] 3a37f000-9acd-0006-870e-393acd9ad801 in the Event Log or usethe command line Get-AppPackageLog -ActivityID 3a37f000-9acd-0006-870e-393acd9ad801At line:1 char:53+ ... | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.I ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : WriteError: (C:\Program File...ppXManifest.xml:String) [Add-AppxPackage], IOException + FullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand
