Many modern MSIX packages rely on dependencies (like the VCLibs runtime or .NET framework). If your MSIX package requires external dependencies, the installation will fail unless you specify them during provisioning. Use the -DependencyPackagePath parameter to include them: powershell
Check existing versions using Get-AppxPackage -AllUsers . If upgrading, ensure your package version number is higher than the currently installed version.
The MSIX package is signed with a certificate that the local machine does not trust.
The MSIX packaging format is the modern standard for Windows applications, offering a clean install/uninstall experience. However, a common challenge for system administrators is that the standard Add-AppPackage command only installs an application for the . install msix powershell all users
If you really mean “run per‑user install for every existing user profile,” that’s (inefficient, error‑prone). Instead, use Add-AppxProvisionedPackage above.
To install an package for all users via PowerShell, you must "provision" it at the operating system level. Unlike Add-AppxPackage , which only installs for the current user, provisioning ensures the app is pre-installed for every existing user and automatically registered for any new users who sign in. Installation Command
You must run PowerShell as an Administrator. Many modern MSIX packages rely on dependencies (like
Add-AppxProvisionedPackage -Online -PackagePath "C:\Path\To\YourApp.msixbundle" -SkipLicense Use code with caution. Verifying the Installation
The MSIX signature chain does not lead to a trusted root certificate in the Local Machine store.
Now go ahead—launch PowerShell as Admin, point to your MSIX file, and provision that app for everyone. If upgrading, ensure your package version number is
