Worst app ever. Don't even bother. It doesn't work. You can waste hours of your life Google-ing the million issues you will encounter only to become more enraged that this "product" even exists in the current useless state. They refuse to fix it and make it worse (if that's possible) with every update. I've now gone from viewing a black box over my screen to not being able to connect them at all. Great job Team Viewer! Fire your whole staff and start fresh, focusing on QA.
