About the key file
A key file is a file with the .key extension that you receive from Kaspersky. The purpose of a key file is to add a license key that activates the application.
You receive a key file at the email address that you provided when you purchased Kaspersky Endpoint Security or ordered the trial version of Kaspersky Endpoint Security.
You do not need to connect to Kaspersky activation servers in order to activate the application with a key file.
You can recover a key file if it has been accidentally deleted. You may need a key file to register a Kaspersky CompanyAccount, for example.
To recover a key file, do one of the following:
- Contact the license seller.
- Obtain a key file on the Kaspersky website based on your existing activation code.
When the application is activated using a key file, an active key is added. A reserve key can be added only by using a key file and cannot be added using an activation code.
