Remote Computer only allows screensharing, no action with mouse or keyboard

Hi,

i reinstalled my dad's PC (Win10+TV12) and since then Teamviewer (when starting a connection) asks him if he wants to allow screen sharing or not. The only other option is to decline that. There is no option to allow also the remote control.

In the settings everything is set to "full control/access"

Anyone an idea whats wrong or which config i am missing? In the past that always worked with the standard settings after installation.

Thanks
