I have a Raspberry Pi in a remote location which I was not able to get to because of Covid. TeamViewer is out of date so I cannot access, it therefore I need to update. I now have a second Pi on site, and I can TeamViewer into that, and then use VNC to get to the first Pi. When I click on the TeamViewer icon I just a small page open with my ID to pass on to a partner. There is also the cog which opens options. Nowhere on the page or in options is there the ability to upgrade the software. Do I have to totally re-install, if so how.
Thanks in advance
Doug
