Should you encounter activation errors such as "The key is already in use", we recommend deleting the license key from the application and activating the product once again.
To delete the key and activate the application again:
Your Kaspersky application will be reactivated.
In case you get the error saying the key file is corrupted, try reinstalling the application. For instructions, see this article.
If the issue persists, contact Kaspersky technical support by choosing the topic and filling out the form.
