I am getting an error that the remote Team Viewer is running an old version which is out of date. Therefore you cannot connect to this Version anymore. I have installed the updated version 14.3.4730 on both the main computer and remote computer. Both running version 14.3.4730.
So I can NOT connect to remote computer via the "Remote Control - Prompt for confirmation" method. This method gives me the out of date error. Instead, I can only remote control via the "Windows Authentication" method.
