How to Activate Kaspersky 2010 Using Key File

By 03-12-2009   Guest PostsTutorials

In this tutorial we will explain the steps involved in activating Kaspersky 2010 using key file. Kaspersky Internet Security 2010 and Kaspersky Anti Virus 2010 are the latest version of Kaspersky Lab. Kaspersky Lab added a lot of powerful features in these new versions, but one thing is missing there – you cannot activate Kaspersky Internet Security 2010 and Kaspersky Anti Virus 2010 using key file.

Key files or activation codes

Security software makers often allow software activation using key files or activation codes. Consumers often find the activation codes easier to use as it can be easily typed in. On the other hand, key files are machine readable and are available as a .key file. They require special instructions to use and are not so user friendly. The use of key files requires special steps which are outlined in this video on the Kaspersky website.

Because this option is not available in “License” menu, you can only activate kaspersky 2010 using activation code. Maybe it is a temporary bug. It is noticed that sometimes while activating Kaspersky 2010 if you type the wrong activation code, and it can sometimes enable the “Activate Kaspersky using key file” option. Then you can use the key file which came with your valid Kaspersky purchase.

Always use a valid Kaspersky key file to activate kaspersky 2010 obtained via official sites or reputed vendors. Never download it through suspected or super cheap websites … or you might regret it

    When trying one of the 2 keys, it comes back to step 3.

    Good walk through but missed a couple of vital steps.

    1. Delete any active trial keys.

    2. Disable any active internet connection.

    …..the it will work flawlessly, even with KIS 2009 keys.
