Few days back We wrote about Kaspersky removing the activation option of its products with keyfile. As I had just the keyfile for Kaspersky Internet Security available with me of the 2009 version whose license was still valid for few weeks more , I tried to find out if i can activate it somehow with the keyfile I had and hence tried to search my old emails where I had stored the Kaspersky Internet security activation code. I was just getting frustrated as I was not sure on how to activate it with the keyfile.
The option of logging into kaspersky account to get back activation code was bit lengthy as I had forgotten the user name, password and almost never logged in there since I activated Kaspersky internet security 2009. On searching i found another license activation code but that was for 2010 Beta version. I just thought, lets see if this works.
When i entered the activation code into my existing Kaspersky Internet security, it said the license isn’t compatible with the product but the screen also showed me the option to browse for the key file. I was delighted to see that option of browsing a key file as it solved my problem. I was able to activate my Kaspersky Internet security on my system using the keyfile. I will just put all this in a proper step by step instructions here on how to do this using a key file.
1. Click activate license from menu.
2. You need to input a valid Beta activation code or any other product valid activation code. After that it will tell you that the license is not valid or it is incompatible with the product.
3. You will see a page like in the image below.
4. You can now browse to a valid Key file on your system and it will complete the activation of your Kaspersky Antivirus or Internet Security.
This step-by-step guide works on all Kaspersky Products with 2010, 2011 and 2012 versions.
