About the key file

A key file is a file with the .key extension, provided to you by Kaspersky. Key files are designed to add a key that activates the application.

You receive a key file via email after purchasing Kaspersky Embedded Systems Security for Windows or ordering the trial version of Kaspersky Embedded Systems Security for Windows.

You do not need to connect to Kaspersky activation servers in order to activate the application with a key file.

You can restore a key file if it has been accidentally deleted. You may need a key file to register with Kaspersky CompanyAccount.

To recover a key file, you should perform any of the following actions:

• Contact the license vendor.
• Obtain a key file from the Kaspersky website based on the available activation code.
