Latest update: February 18, 2022 ID: 13829
This article concerns:
  • Kaspersky Basic, Standard, Plus
  • Kaspersky Internet Security
  • Kaspersky Anti-Virus
  • Kaspersky Total Security

Should you encounter activation errors such as The key is already in use, we recommend deleting the key from the application and activating the application once again.

Before deleting the key from the application, check whether the activation code has been saved. You will not be able to reactivate the application without an activation code. To save your activation code, connect the application to My Kaspersky. See this article for instructions. Information about the license will then appear in the Subscriptions section of My Kaspersky.

To delete the key and activate the application again, follow the instructions below. 


For Kaspersky Basic, Standard, Plus


For Kaspersky Internet Security, Kaspersky Anti-Virus, Kaspersky Total Security
