If you are managing a standalone device or a small environment without KSC:

| Problem | Solution | |---------|----------| | Activation code verification fails | Contact your software vendor or Kaspersky partner for verification | | Application won't activate due to incorrect system date/time | Correct the system date/time before attempting activation | | Unable to activate in isolated network | Use key file activation instead of activation code, or configure proxy server through Kaspersky Security Center | | Activation takes excessive time | Interrupt the ongoing activation and retry using the activation wizard interface directly | | License shows expired despite recent purchase | Verify that the license was properly added to Kaspersky Security Center key storage and distributed to devices |

Using unauthorized software can lead to legal issues and breaches of data protection regulations.
