Hey guys i got a doubt regarding Kaspersky internet security 2015 license recently i bought this and accidentely recieved two copies of it so i was wondering if i use 1 license this year them will i be able to use the other license of 2015 next year on kaspersky internet security 2016 ?
if they're different license keys yes. If its two copies using the same key (i.e a multi user license) then no.
To add on to Loony's statement, if you use the second key, you will only be able to use it to add on another year to Kaspersky 2015. It will not work on the 2016 version.
