Find PowerShell in the Start menu, right-click on it, and then select the option “Run as Administrator”
Navigate to the appx file location using the below command. Replace c:\path_to_appx\directory with the directory path to the .appx file.
cd c:\path_to_appx\directory
After navigating to the directory, use this command to install the .appx file. Replace “file.appx” with the appx file name.
Add-AppxPackage “.\file.appx”
Or
Add-AppxPackage -Path “.\file.appx”
When you execute the command, the app will install (normally quite quickly). You will not receive any confirmation message in the PowerShell window. You will be able to search for the installed app on the Start Menu.
