Entering your License Key during activation

Automatic updates are important for your security. ESET Smart Security Premium will only receive updates once activated.

When entering your License Key, it is important to type it exactly as it is written. Your License Key is a unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the license owner and activation of the license.

We recommend that you copy and paste your License Key from your registration email to ensure accuracy.

If you did not enter your License Key after installation, your product will not be activated. You can activate ESET Smart Security Premium in the main program window > Help and support > Activate License.

ESET Windows home product full licenses are not free.
