Solution: The digital signature on the MSIX is not recognized. You must install the signing certificate into the local machine’s "Trusted People" or "Trusted Root Certification Authorities" certificate store before deploying the app. Conclusion
Standard double-click installations only install the application for the currently logged-in user. To provision an application for everyone, system administrators must turn to PowerShell.
: Alternatively, you can use dism.exe to provision packages, which is often used in imaging workflows:
The native Appx and Dism modules must be available (included by default on Windows 10 and Windows 11). install msix powershell all users
Once provisioned, you can manage or verify the installation using these administrative commands: Verify Installation : To see if the package is correctly provisioned, use Get-AppxProvisionedPackage powershell
To force an immediate registration for every currently logged-in profile alongside provisioning, combine Add-AppxProvisionedPackage with Add-AppxPackage : powershell
Add-AppxPackage -Path "C:\Path\To\YourApp.msix" Solution: The digital signature on the MSIX is
This command achieves the same result as the Add-AppxProvisionedPackage PowerShell cmdlet, as it interfaces directly with the underlying Windows provisioning system.
When managing MSIX packages, there are two distinct PowerShell cmdlets you need to know:
After running the deployment commands, verify that the application has been successfully provisioned system-wide. Check Provisioned Packages (System Level) When managing MSIX packages, there are two distinct
Before jumping into the code, it's crucial to understand the fundamental design of MSIX. Unlike traditional MSI packages, which support both per-user and per-machine installations, MSIX is designed primarily for per-user installations. This means an MSIX package is usually registered to a specific user's profile after they log in, but the actual application's binaries are stored in a shared, protected system location ( %ProgramFiles%\WindowsApps ).
: For users already signed in, the app typically appears immediately without requiring a logout. Installation Path : The app files are stored in the protected %ProgramFiles%\WindowsApps directory. Microsoft Learn Removing a Machine-Wide Package
Add-AppxProvisionedPackage is more for OS image customization (Windows PE, unattend.xml). For everyday deployment, Add-AppxPackage -Scope Machine is preferred.
