When you activate a Kaspersky lab product with a renewal activation code, the application checks if a license for your Kaspersky Lab product has been activated on that computer before:
If the code that you entered corresponds to your Kaspersky Lab product, the license will be renewed for the full period. You may encounter an error in the following cases:
Select the "I agree to decrease license validity period by ..." check box and click Register and continue.
The license term will be reduced.
If you have a compatible license for your Kaspersky Lab product you used earlier, but the renewal license validity period is still shorter than it should be, please contact Kaspersky Lab Technical Support via My Kaspersky. In your request, give a detailed description of the issue and provide your previous license key or activation code as well as the new license code.
