Solutions
Solution 1: Remove Existing Package Registration
- 1Find the existing package:
- 2PowerShell as Admin:
- 3Get-AppxPackage -AllUsers *appname*
- 4Note the full PackageFullName
- 5Remove for all users:
- 6Remove-AppxPackage -Package "PackageFullName" -AllUsers
- 7If that fails with access denied:
- 8Remove-AppxPackage -Package "PackageFullName" -AllUsers -ForceApplicationShutdown
- 9Also remove provisioned package:
- 10Get-AppxProvisionedPackage -Online | Where-Object {$_.DisplayName -match "appname"}
- 11Remove-AppxProvisionedPackage -Online -PackageName "name"
- 12After removal: retry installation from Store
Solution 2: Reset App Package Database
- 1If individual removal fails:
- 2Reset the Windows Store cache:
- 3CMD as Admin: wsreset.exe
- 4Wait for Store to open (may take 30+ seconds)
- 5Reset Microsoft Store app itself:
- 6Settings → Apps → Installed apps → Microsoft Store
- 7⋯ → Advanced options → Reset
- 8Re-register all Store apps:
- 9PowerShell as Admin:
- 10Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -ErrorAction SilentlyContinue}
- 11This re-registers all packages without removing data
- 12Retry the specific app installation
Solution 3: Clean Package Registration via DISM
- 1For deep package registration issues:
- 2Check provisioned packages:
- 3DISM /Online /Get-ProvisionedAppxPackages | findstr /i "appname"
- 4Remove if found:
- 5DISM /Online /Remove-ProvisionedAppxPackage /PackageName:"full.package.name"
- 6Clean component store:
- 7DISM /Online /Cleanup-Image /StartComponentCleanup
- 8sfc /scannow
- 9Restart PC and retry installation
- 10Nuclear option — reset Store completely:
- 11PowerShell as Admin:
- 12Get-AppxPackage Microsoft.WindowsStore | Remove-AppxPackage
- 13Then reinstall Store:
- 14Get-AppxPackage -AllUsers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
- 15Open Store and install the app fresh
