Applies to Kaspersky PURE
The error "License validity period has expired" might appear on the screen during activation of Kaspersky PURE.
Most probably the validity period for the key/activation code has expired. In order to prolong the license you should go to the following page: http://www.kaspersky.com/renew
In some cases the error may be caused by the incorrectly set system date. You can find detailed instructions on how to check the system date and time in KB3508.
When the system date is set correctly, try to activate the application.
If the recommendations described above did not help to resolve the problem, try to activate later (in about an hour).
If the error keeps repeating, create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service. In the request describe your problem in all details.
