Activate the auto update for your TeamViewer full version, in order to always be able to use the latest TeamViewer features.
If activated, the latest version within your major software release is installed automatically. This way, you always use the latest TeamViewer version with all its features. TeamViewer sessions to other TeamViewer versions are possible without restriction.
We recommend activating the option if you use the Remote Update possibility within remote control sessions. If deactivated, it is not possible to do a remote update for the device.
How to enable the auto update for TeamViewer
Open the TeamViewer full version
Click Extras --> Options.
Choose All updates under Install new versions automatically.
