Where do I find my license key?

I have another antivirus on my laptop and it is running out. I want to put Comodo on there as well. I can not find my license key though. Also I have Internet Security Premium and I was wondering does it cover 2 computers?

CIS Premium is free; there is no license key to register.

You can install CIS Premium on as much PC you want.

Okay, Thanks. For some reason I thought I had a paid subscription.
