Activation failed

If the activation of ESET Endpoint Antivirus is not successful, the most common scenarios are:

  • License key is already in use.
  • You have entered an invalid license key.
  • Information in the activation form is missing or invalid.
  • Communication with the activation server failed.
  • No connection or disabled connection to ESET activation servers.

Verify that you have entered the proper license key or attached an Offline license and attempt to activate again.

If you are unable to activate, our welcome package will walk you through to common questions, errors, problems about activation and licensing (available in English and several other languages).
