A license update is available only to users who previously have used any version of a Kaspersky Lab commercial product.
For your information!
Note! If the previous license is, for example, for 1 device and now you are purchasing a license update for 2 devices, then the license term for the second device will be shorter by 33%! If you want a license for the second device with full license term, you will need to purchase a new license for that device.
If you are using a trial version of a product, you must purchase a new license.
To buy a license update, choose "Licence renewal" at the product page.
Then follow the instructions in the section "How to make an order"
