I downloaded Netshred 5.3.2 upgrading from 4.7.7. Is my license from the previous version valid for 5.3.2?
Version string are Major.Minor.Fix, typically Minor and Fix revisions are free (the exception is subscriptions in which case Major revisions are also included in the subscription). So if you have an Active NetShred X annual subscription its free, if you don’t have an active NetShred X subscription then you need to purchase one.
