How to distinguish the versions of Kaspersky (Kaspersky installed on the computer and no longer install the original file), the key of the Preview Edition is nothing else, with TR or Commercial Edition, signs of recognition, thanks admin
Cause you are using Kaspersky Beta version and 2019 Beta is over thats why you have 54 days (Kaspersky provide beta keys till the end of beta). Now Kaspersy 2019 is in TR stage will be commercial final soon. I suggest to install TR edition and activate 45 days with OEM Trial license, every 45 days use trial reset to gain another 45 days and so on.... All you need provided in this topic just look on this page...
