Can't install paid Internet Security for 3 computers on 3rd computer

Hello Jerry,
I can see that you have already contacted our technical support team via chat. They had provided instruction to activate AVG Internet Security, you was rebooted your computer and chat got disconnected. May I know if your AVG Internet Security is working fine on your 3rd computer. If not, then I request you to follow the email instruction (which has been sent by the chat support team) to connect with us again.
Best regards,
Alok.
