In some cases the error "Activation code is invalid for this region" may appear on the screen during the activation process.
The error can appear if you try to activate your application using an activation code in one region (country), but the activation code you use is intended for use in another region (country). For example, you bought Kaspersky Internet Security via E-Store in India, but you try to install and activate the application in the United Kingdom.
In order to eliminate the problem, you need to install and activate your Kaspersky Lab product in the region (country), where you bought the application.
If you activate Kaspersky Internet Security 2013 in the region (country), where you bought the application and/or the recommendations given above have not helped you to eliminate the problem, then you are recommended to create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service.
