How to activate Kaspersky Internet Security 20

Hello, can u tell me how can i activate my kaspersky internet security after i use all attemp, but i still have like 100+ left.

Hi, i have 2 subscription at the same PC, the old activate will end at the end of this month and the new one i just added few days ago but i can't choose it to be the main actvite instead of the one witch is about to end.. Can you say what to do in that case..?!

I have installed the trial and have already purchased a one year license. Does activating it right now add 1 year to the trial or I need to wait until the trial expire?

Do I need to make a karspersky account to renew my license?

My Kaspersky Internet security and Kaspersky connection security's shortcuts had gone suddenly and I can't find the program in the search bar in my PC , Can I re-install Kaspersky Internet security ? ( Can I use the same activation code that I activated with at the first place?)

Is trial version of Kaspersky Internet Security 2020 good like a purchased one?
