When you purchase activate avast antivirus from within an Avast application, your subscription is automatically activated on the Windows PC you use to make the purchase. A subscription purchased through another Avast sales channel, such as the Avast Store, is also automatically activated when you receive and install the preactivated setup file. If your subscription does not activate automatically, you will need to manually activate using either a valid activation code (sometimes called a subscription code or voucher code), or license file, or via your Avast Account that is registered with the same email address you used to make the purchase.
Thanks for the tip on this service. That year, unfortunately, I also had to face this problem, in the official documentation it is not entirely clear how to solve this problem, especially if you are not an advanced user, then a guide on Twitch helped me in which the author showed how to activate avast antivirus even if this error occurs, as well as how to solve it. I don’t remember the name of that video anymore, but I remembered for sure that the author had about 24 thousand subscribers on the channel, and I’m sure that he used https://soclikes.com/buy-twitch-followers to buy subscribers.
