Activation failed
In the case activation of ESET Endpoint Security was not successful, the most-common possible scenarios are:
•License key already in use
•Invalid License key. Product activation form error
•Additional information necessary for activation is missing or invalid
•Communication with the activation database failed. Please try to activate again in 15 minutes
•No or disabled connection to ESET activation servers
Make sure 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).
