For some inexplicable reason, Teamviewer seems to have disabled even this functionality.
In the older days of Teamviewer, there used to be a method where you could update a remote install of Teamviewer by supplying the administrative credentials, and then letting Teamviewer essentially perform an unattended in-place upgrade.
These PCs are in remote locations that I WILL NOT HAVE PHYSICAL ACCESS TO any time soon.
I DO NOT want to give the remote users administrative access.
I DO have the administrative credentials to these computers.
The remote users DO NOT have administrative access to their computers.
I now also learn that TeamViewer has completely disabled all functionality with these older versions of Teamviewer.
The time has come that I now need to support several of these PCs.
Most of these installs have older versions of TeamViewer that are now deprecated.
I have TeamViewer installed on several Windows PCs (friends, family, former and current coworkers) that I figured I might need remote access to some day.
