Start to install Kaspersky already purchased - you just need to create a Kaspersky account and then redeem your activation code inside the account. Then download and run your program. All the steps to install Kaspersky already purchased are described in the below section properly.
First of all, to activate the commercial version of Kaspersky Anti-Virus 2016, use a 20-digit activation code. You can find the activation code on the Quick Start Guide if you have a boxed version or in the message sent to your e-mail if you bought the code in the online store. If you do not have an activation code, buy it at the Kaspersky Lab official e-Store.
So, now I expect you have an activation code. Go to my.kaspersky.com
