Licensing limitations

The license lifecycle in the offline and online licensing modes is the same. Kaspersky Scan Engine can be used until a certain date, which is called the expiration date. Kaspersky Scan Engine uses a key file or an activation code to determine the expiration date.

If the expiration date has passed, the key file or the activation code expires and you can only use Kaspersky Scan Engine with licensing limitations.

Kaspersky Scan Engine can have the following licensing limitations:

If the time received from KSN is at least one day later than the expiration date of your key file or activation code, Kaspersky Scan Engine will work but you will not be able to use File and URL Reputation Checking.
If the release date of the anti-virus database is at least three days later than the expiration date of your key file or activation code, Kaspersky Scan Engine will not work.

Removing licensing limitations in online licensing mode

To remove the licensing limitations, you can do the following:

If your copy of Kaspersky Scan Engine was not connected to the Internet for the last 15 days or more, the licensing limitations are most likely caused by outdated licensing information. To remove licensing limitations, allow Kaspersky Scan Engine to connect to the Internet.
To prevent this problem, make sure that Kaspersky Scan Engine always has access to the Internet.
If your activation code has expired, obtain a new activation code and activate Kaspersky Scan Engine with it. To activate Kaspersky Scan Engine with a new code, your copy of Kaspersky Scan Engine must be connected to the Internet.
If other options are not possible, use an earlier version of the anti-virus database to initialize Kaspersky Scan Engine. This method does not remove limitations placed on File and URL Reputation Checking functionality.

Removing licensing limitations in offline licensing mode

To remove the licensing limitations, obtain a new key file and activate Kaspersky Scan Engine with it.
