Your ESET home product is updated at least daily with new virus detections and occasional program component upgrades. These updates will fail if your product is not activated using a License Key.
If you did not add a license key during installation, or your ESET product is still not activated, follow the steps below:
When the product activation screen appears, click Use a purchased License Key.
Type or copy/paste your ESET-issued License Key into the License Key field and click Continue. Make sure to type the License Key exactly as it is, including the hyphens. If you copy/paste the license, ensure that you do not accidentally select additional space around the text.
Click Done. You have successfully activated your product.
