About the license key file

A license key file is a file with the KEY extension that you receive from Kaspersky. The license key file is used to add a license key that activates the corresponding application functionality.

You receive a license key file after you purchase Kaspersky Industrial CyberSecurity for Networks. The method used to receive a license key file is determined by the Kaspersky distributor from whom you purchased the application (for example, the license key file may be sent to the email address you specify).

You can also add a license key from a license key file that was received when purchasing a previous version of Kaspersky Industrial CyberSecurity for Networks. A license key can be added to the application before its expiration date.

You do not need to connect to Kaspersky activation servers to activate application functionality with a license key file.
