I switched from 2016 to 2017 beta and it cured the safe pay crash but now they tell me i only hyave 91 days and I bought 2016 this April...sounds like the shaft to me..
Don't use the beta installer, it doesn't accept commercial codes. Uninstall the beta, download KIS 2017 release from http://products.kaspersky-labs.com/products/english/homeuser/kis2017/ and apply your code.
2017 Final released, see: https://www.wilderssecurity.com/threads/kaspersky-av-is-ts-2017.384563/page-3#post-2605506
