Fix Fix Windows Error 0x80073D22 (App Package

Symptoms

You might be experiencing this problem if you notice:

•Microsoft Store app installation fails with error 0x80073D22
•App update fails with "deployment failed" and error 0x80073D22
•Sideloaded app package blocked with this error code
•Store shows "Something happened on our end" with 0x80073D22
•MSIX or Appx package install rejected by policy
•Error appears after Windows Update or policy change

How RescuePC fixes 0x80073D22 when AppX deployment is blocked by policy

Error 0x80073D22 (DEPLOYMENT_E_BLOCKED_BY_POLICY) means Windows refused to install or update an AppX/MSIX package because of a Group Policy or AppLocker rule, an Application Identity service issue, or a sideload restriction. RescuePC inspects each policy layer so the right one gets adjusted instead of disabling all protection.

→Reads Allow/Deny AppLocker rules under HKLM\SOFTWARE\Policies\Microsoft\Windows\SrpV2
→Verifies the Application Identity (AppIDSvc) service is running so AppLocker can evaluate
→Checks the AllowAllTrustedApps and AllowDevelopmentWithoutDevLicense Settings keys
→Confirms the Microsoft Store policy (RemoveWindowsStore, DisableStoreApps) is not pinned
→Captures Get-AppxLog output for the failing package so the offending rule is identifiable

Most useful when a domain-joined PC fails to update Microsoft Store apps, when sideloaded MSIX packages refuse to install on Windows 11, or when a managed device throws 0x80073D22 immediately on Add-AppxPackage.

Common Causes

⚠Enterprise policy blocking app package deployment
⚠Sideloading disabled in Windows Settings
⚠Group Policy restricting Microsoft Store app installation
⚠Windows Defender Application Control (WDAC) policy blocking the package
⚠Package signature not trusted by the system
⚠MDM (Mobile Device Management) profile restricting app installs

Solutions

Solution 1: Enable Sideloading and Developer Mode

1Open Settings → Privacy & security → For developers (Windows 11)
2Or: Settings → Update & Security → For developers (Windows 10)
3Enable "Developer Mode" or at minimum "Sideload apps"
4If the toggle is greyed out: Group Policy is blocking it
5Accept the warning prompt if one appears
6Restart the computer
7Try installing the app again
8If this was the issue: the app package needed sideloading permissions

Solution 2: Check Group Policy for Store Restrictions

1Open gpedit.msc as Administrator
2Navigate to: Computer Configuration → Administrative Templates → Windows Components → App Package Deployment
3Check "Allow all trusted apps to install" — set to "Enabled"
4Check "Allow development of Windows Store apps..." — set to "Enabled"
5Also check: Computer Configuration → Administrative Templates → Windows Components → Store
6Ensure "Turn off the Store application" is "Not Configured"
7Run: gpupdate /force
8Restart and try the installation again

Solution 3: Reset Microsoft Store and Clear Cache

1Press Win+R → type: wsreset.exe → Enter
2Wait for the Store to open (this clears the cache)
3If that doesn't help: open PowerShell as Admin
4Run: Get-AppxPackage Microsoft.WindowsStore | Remove-AppxPackage
5Then reinstall: Get-AppxPackage -AllUsers Microsoft.WindowsStore | Foreach {Add-AppxPackage -Register "$($_.InstallLocation)\AppxManifest.xml" -DisableDevelopmentMode}
6Restart the computer
7Open the Store and try installing the app again
