unattended connection from PC to Android

for the purpose of attended connectin from PC to Android the following was done:

Using corporate license on PC, on the android TV HOST app was installed however when connecting the PC shows the following message:

you are trying to connect to a mobile device running the teamviewer quicksupport app, to use this func... additional mobile device support license ..

my question is first why it tells me i have quicksupport app installed where i have the tv host app installed (i followed the instructions for unattended connection guide) 

and second question, unattended connection requires a license?
