The activation code is alpha-numeric grouped as 5 5 5 5 combinations.
The license key is alpha-numeric grouped as 8 4 4 4 12 combinations.
Unfortunately, here in the Community portal we cannot resolve license / product activation issues.
For any activation code, licensing issues, it's necessary to contact Kaspersky Lab Technical Support.
https://support.kaspersky.com/b2c, choose your region/location, select your choice of contact, phone, online chat (if it's available in your region), or log into your MyKaspersky account, create an incident request, use template "activation & liscense issues" https://my.kaspersky.com/techsupport#/requests/new
