Microsoft Teams Room version 5.2.115.0 bug: Teams Room account can't login

When you installed it manually as the Skype user, did you get an access denied error? We did and that’s how we knew we had a setting blocking the install and eventually tracked down what it was. If yours just installed fine manually you might have some other cause as to why new teams isn’t installing automatically. Good luck!

Hi Brandon,

Thanks for this reply.

I tried this 'manual install new teams' with one of our customers rooms, and this worked.

You describe a registry key that was set to '1' by Intune. The BlockNonAdminUserInstall registry key. When I take al look in different teams Rooms we manage, there isn't such a key available. So I have to add this registry key to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx

Am I correct? And if I add this, the rest of the update wil go by itself?

We manage our rooms via datto rmm, not via Microsoft device manager, so we can't use your methode to add the key as described in the article. But from datto we can do this via script.

Thanks, I'll keep these notes. As of right now, all our rooms are working with the older version but if they happen to auto update, I'll have to give this a try.

So if we have New Teams installed MTR 5.2.115.0 should work?

There is a specific Teams Room version of New Teams that has to be installed it seems. Microsoft has given me the process to manually sideload it in case the automated install has failed. But even doing it manually with these instructions didn't work until we removed the setting that was blocking non admin package installs because the skype user didn't have permission to do the install. And after fixing that setting a manual install isn't really needed because it should be able to install automatically as it is supposed to.

You can run this command as admin on a device to see if you are missing the New Teams package:

Run logged on as adminstrator:

Get-AppxPackage -name *teams* -User skype

If the package is missing the output will be blank.

How to Side-Loading Package via Impersonation:

Logged on as Admin:

1. Download PSTools
2. Download the https://statics.teams.cdn.office.net/production-windows-x64/24241.400.3089.3663/MSTeams-Rooms-x64.msix

Procedure:

1. Copy the msix package in as easily accessible directory (we will be using C:\Users\Skype for this)
2. Place PSTools in as easily accessible directory (we will be using C:\Users\Admin\PsTools for this )
3. Launch PSExec (this is launching a powershell session on the Skype user. DO NOT SKIP)
   • Open an admin powershell
   • Run C:\Users\Admin\PsTools\PsExec.exe -u Skype powershell
   • Press enter when prompted for the password - if you get an error that blank passwords are not allowed, set the HKLM\SYSTEM\CurrentControlSet\Control\Lsa\LimitBlankPasswordUse key to 0 and try running PsExec.exe again.
4. Run cd C:\Users\Skype in the powershell prompt that comes up
5. Run WHOAMI (one word), it should output COMPUTERNAME\Skype => this shows you are signed in as user Skype
6. Run Add-AppxPackage .*packageFolder*packageMSIX\ (or the folder where you put in the MSIX before)**
7. Restart

So if we have New Teams installed MTR 5.2.115.0 should work?
