My first question would be, why do you wan tto install it if it is already installed... Maybe more a patching question? Or you may have to create a removal package first.&nbsp;
</div>

<div>
Well, we want a standardized installation for all computers.&nbsp; It will make things easier to trouble-shoot later.

<div>
Yea, I can imagine. As I said, one option is to uninstall and to reinstall. The other option is to use GPOs for the configuration. The third option would be to splitt is up into a basic installation and a customizing installion. For the clients, which already have Teams installed, you apply only the customization package. Im not aware about the capability of Zenworks, but most of the installers and distribution tools are capable in that way.&nbsp;

What does this code do?&nbsp; It is from:&nbsp;<a href="https://sysmansquad.com/2021/01/26/trigger-teams-installer-for-user-after-machine-wide-installer/" rel="ugc">Trigger Teams Installer for User After Machine Wide Installer - Systems Management Squad (sysmansquad.com)</a>&nbsp; <pre><code class="code-10 nolinks" id="code-20-43287113-1">&lt;#
.SYNOPSIS
&nbsp; &nbsp; Launch the Teams install as the logged in user via a scheduled task
.DESCRIPTION
&nbsp; &nbsp; This script will create a scheduled task if one is not found which is used to
&nbsp; &nbsp; install Microsoft Teams as the logged in user. This scheduled task executes
&nbsp; &nbsp; the Teams.exe found in %ProgramFiles% so that a user can start using Teams
&nbsp; &nbsp; shortly after the Machine Wide installer completes instead of having to 
&nbsp; &nbsp; log off and back on.
.NOTES
&nbsp; &nbsp; Generally used as a script that runs after a Teams Machine Wide Installer completes

Its written in the description. &nbsp; &nbsp; This script will create a scheduled task if one is not found which is used to &nbsp; &nbsp; install Microsoft Teams as the logged in user.

This looks promising, But the below did not work for me, if Teams was already installed under my username. &nbsp;How can I remove teams (execute a script) before the installation is applied? <a href="https://techcommunity.microsoft.com/t5/healthcare-and-life-sciences/getting-started-with-microsoft-teams-enterprise-deployment-part/ba-p/714584" rel="ugc">Getting Started with Microsoft Teams Enterprise Deployment, Part 1 - Microsoft Tech Community</a> (<a href="https://techcommunity.microsoft.com/t5/healthcare-and-life-sciences/getting-started-with-microsoft-teams-enterprise-deployment-part/ba-p/714584" rel="ugc">https://techcommunity.microsoft.com/t5/healthcare-and-life-sciences/getting-started-with-microsoft-teams-enterprise-deployment-part/ba-p/714584</a>_ <a href="https://docs.microsoft.com/en-us/microsoftteams/msi-deployment" rel="ugc">Install Teams using Microsoft Endpoint Configuration Manager - Microsoft Teams | Microsoft Docs</a> (<a href="https://docs.microsoft.com/en-us/microsoftteams/msi-deployment" rel="ugc">https://docs.microsoft.com/en-us/microsoftteams/msi-deployment</a>) <h2>Clean up and redeployment procedure</h2>If a user uninstalls Teams from their user profile, the MSI installer will track that the user has uninstalled the Teams app and no longer install Teams for that user profile.

I am trying to deploy Microsoft Teams enterprise wide, for mass installation on different computers.

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.

Web conferencing describes various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers. Popular titles include GoToMeeting, Cisco WebEx, Microsoft Lync, TeamViewer and Skype.
