I entered credit card info for and now am asked for license # or activation code and I was not given either one of these.
What do I do now?
Check your email.
The license will be send to you as soon as the transaction is completed.
also see FAQ section for info http://www.avast.com/faq.php
ok, I double clicked the attachement, but now get message that the license is invalid or banned and there is a feature missing from the attachment
getting very frustrated, I’ve never had issues like this with Avast in the past
Save the attachment to your system.
Open avast > settings > subscription > insert license file
