chrisbuesold : I tried to update the SRSv2 / MTR app offline using the URL you provided. Your link is broken, it contains a typo: https://docs.microsoft.com/en-us/microsoftteams/room-systems/room-systems-v2-operations I logged into the SRS using the admin user, downloaded the MSI, and extracted the content on the SRS machine, under a new folder c:\temp\SRS After that, I tried the powershell example, looked like this: Add-AppxPackage -Update -ForceApplicationShutdown -Path 'c:\temp\srs\$oem$\$1\Rigel\x64\Ship\AppPackages\*\*.appx' -DependencyPath (Get-ChildItem 'c:\temp\srs\$oem$\$1\Rigel\x64\Ship\AppPackages\*\Dependencies\x64\*.appx' | Foreach-Object {$_.FullName}) But it failed, as expected: the add-appxpackahe could not update the SRS app, as it found it not installed. As I was running the PS command under the admin user account, that is no surprise: the SRS app is normally running under the "Skype" user. But the example above does not tell you how to target the "Skype" user instead of the currently logged on user. Does anyone have any idea about this?
