Download App Installer - New Teams Issue
Some new laptops are having an error when trying to download the Teams for Work app. Make sure the App Installer is Installed/updated in the Microsoft Store. If you are unable to Install or Update the App Installer from the Microsoft Store, run this command on PowerShell as admin and that should fix it. I had an issue getting the App Installer updated on a new computer and this command allowed me to download the new Teams for Work.
