Hello John,
From your account, I see that you have already purchased AVG Internet Security - Unlimited (2 years subscription), which can be installed in Multiple devices (windows computers, mac computers and android devices). This product does not require a license number for activation, as it is activated using your AVG MyAccount that was created during your purchase. Please follow the instruction (http://support.avg.com/SupportArticleView?urlname=Download-and-install-AVG-Protection) to download/install/activate AVG Internet Security - Unlimited on your new computer.
Best regards,
Alok.
