When activating a Kaspersky Lab product, you may receive the error message “Cannot add key if it has expired”.
Error cause and solution
Most likely, the error occurs because your license has expired. To fix the error:
- Check the license expiration date. See this detailed guide for instructions.
- If the license has expired, renew it. To find out how to renew a license, see this article.
- If the license has not expired, check that the system date is set correctly on your computer. If the system date is wrong, adjust it and try to activate the application once again.
If the method did not help, retry to activate the application later (in about an hour).
What to do if the issue persists
If the issue persists, send a request to Kaspersky Lab technical support via My Kaspersky. In your request, please provide a detailed description of the problem.
