Solutions
Solution 1: Clear Microsoft Store Cache
- 1Press Win+R → type wsreset.exe → press Enter
- 2This clears the Store cache — a blank Command Prompt window opens then Store launches
- 3Wait for the Store to open fully
- 4Try installing the app again
- 5If that doesn't work, also clear the Store cache folder:
- 6Navigate to: %LocalAppData%\Packages\Microsoft.WindowsStore_8wekyb3d8bbwe\LocalCache
- 7Delete all contents of the LocalCache folder
- 8Restart and retry the installation
Solution 2: Re-register Store Apps
- 1Open PowerShell as Administrator
- 2Re-register all Store apps:
- 3Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}
- 4Ignore red errors — they're normal for system apps that can't be re-registered
- 5If a specific app fails, remove it first then reinstall:
- 6Get-AppxPackage *appname* | Remove-AppxPackage
- 7Then install fresh from Microsoft Store
- 8Restart the computer after re-registration
Solution 3: Repair Windows Store Component
- 1Open Settings → Apps → Installed apps
- 2Find "Microsoft Store" → click ⋯ → Advanced options
- 3Click "Repair" first — if that doesn't fix it, click "Reset"
- 4Reset clears all Store data including sign-in — you'll need to sign in again
- 5Also repair system files:
- 6CMD as Admin: sfc /scannow
- 7Then: DISM /Online /Cleanup-Image /RestoreHealth
- 8Restart and retry the Store app installation
