Using the Lifesize Microsoft Outlook Add-In Installation Package (MSI)
The MSI file makes it easy for you to deploy the Lifesize Microsoft Outlook Add-In throughout your organization, and once it is installed, updates are automatic. Download the MSI file for Windows deployments of the new Outlook add-in from the Admin Console.
When run, the MSI copies setup.exe, outlook.bat and outlook.vbs files to the %PROGRAMFILES(X86)%\Lifesize Outlook Installer folder. It also inserts a "Run" key into the Windows HKLM registry that runs this installer when any user logs into the machine.
When a user logs in next (after a reboot or logout), setup.exe runs and downloads the VSTO manifest, installing the add-in into a VSTO ClickOnce (GUID-keyed) folder in %LOCALAPPDATA%\Apps\2.0. When Outlook runs, it loads the add-in from this location. ClickOnce automatically updates the add-in when it detects a new version at https://outlook.lifesizecloud.com.
