How to add a computer to the subscription?

I have the paid Avast Internet Security for 3 computers. I recently reinstalled Windows in one of them and used the Avast offline installer, but I found no way to declare it to the subscription. The trial period has expired and the only way it offers to activate is purchasing. I also went to my.avast.com and don’t see how to add the PC, I bet some years ago it was possible there.
What are the steps to do that?
Thank you!

Asyn, sorry I forgot to reply you. Yes, it worked, thank you!

Thanksgod forums exist, big companies often overlook small details that can have a nasty impact on customers experience. How on earth is not a FAQ covering this elemental question? I searched on my.avast.com , on subscriptions.avast.com I tried “Necesita volver a descargar?” (Do you need to download again?) and installed it in the other PC but worked just as a trial.

You’re welcome.

Just in case someone else happens to suffer the same:

  • Last time I reinstalled Windows, installed the trial Avast Premium Security, went to www.avast.com/resend-license-paid.php , they sent me an email with the license.avastlic , run it, and I got my paid Avast running again.
  • Now, the same. But this time I never received the email with the license (even in the Spam folder), no matter how many hours I waited, on two different days. Has Avast changed the procedure again??? By trial and error, this worked:
    In https://subscriptions.avast.com/ I can copy the Activation Code.
    Open Avast, and I can’t find where to paste it, all I find is Buy! Buy! Buy!
    How come I did not think of this before?: execute the previous license.avastlic !!! No, it didn’t work, maybe the Code expired or was for a single use.
    But… at least it gave me a box to enter the Code. Voilà! I also could reinstall the SecureLine VPN.

Avast may be a great antivirus. But the customer interface is wanting. On top of that, as soon as I reinstalled it they added (without my consent) the SafePrice plugin, and their Secure browser. Not only that, it became the default browser and opens when starting Windows (had to kill it with msconfig).
Excuse me for the off-topic but I am getting increasingly disgusted about Avast.
