How to link EasyPass & 2nd computer to paid subscription?

I keep feeling like I must surely be overlooking something incredibly obvious, but…

I installed Avast free version (on 2 computers) and was very happy with it. Bought the paid version for 2 computers + EasyPass. The paid antivirus/anti-malware appears to have installed on the machine I was using when I made the purchase, but I was never prompted to install the EasyPass… though somehow it seems I ended up with a “trial” version. I’ve never managed to find a way to synch up the trial version with the paid license, and now it’s been prompting me that it will expire in 9 days.

I’ve also never figured out how to synch up my 2nd computer with the paid license.

Kind of wishing I hadn’t paid – things were simple with the free version and worked well. I just appreciated the software and thought I should support it with some $.
