TeamViewer is a screen-sharing and remote collaboration product made by TeamViewer GmbH. TeamViewer can be used to provide online support to your endusers. It isn't included in the images by default, but there's an easy mechanism available to load the official binaries during boot time if needed:
2) put the package on any webserver in your environment, or use the Virtual Appliance to host the file
3) finally, the resulting link of the TeamViewer package needs to be configured for the parameter "Extension -> Teamviewer URL" in the client configuration, so that the enpoints can properly access the necessary files during boot time
4) reboot the clients once, afterwards, TeamViewer is available locally on each device and ready for use
It could also be configured as a connection, which then offers a desktop icon and/or a start menu entry to execute the application directly from the desktop, as an alternative to the hotkey-based start.
