Product activation

After installation is complete, you will be prompted to activate your product.

There are several methods for activating your product. Availability of a specific activation scenario in the activation window may vary depending on the country and the means of distribution (ESET web page, installer type .msi or .exe, etc.).

You can activate ESET Endpoint Antivirus in the main program window > Help and support > Activate product or Protection status > Activate product.

You can use any of the following methods to activate ESET Endpoint Antivirus:

  • Use a purchased License Key—Unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the license owner and for activation of the license.
  • ESET HUB—An ESET HUB account which you have to create. ESET HUB is a central gateway to the ESET PROTECT unified security platform. It provides centralized identity, subscription and user management for all ESET platform modules. You can use this option to activate ESET Endpoint Antivirus also with older license management tools: ESET Business Account or ESET MSP Administrator.
  • Offline License—Automatically generated file that will be transferred to the ESET product to provide license information. If a license allows you to download an offline license file (.lf), that file can be used to perform offline activation. The number of offline licenses will be subtracted from the total number of available licenses. For more details about the generation of an offline file see the ESET Business Account Online user guide.

Click Activate later if your computer is a member of managed network and your administrator will perform remote activation via ESET PROTECT. You can also use this option if you would like to activate this client at a later time.

If you have a Username and Password used for activation of earlier ESET products, convert your legacy credentials to a license key.

You can change your product license at any time in the main program window > Help and support > Change license. You will see the public license ID used to identify your license to ESET Support.


ESET PROTECT can activate client computers silently using licenses made available by the administrator. For instructions, see the ESET PROTECT Online help.
