If you did not add a license key during installation, or your ESET product is still not activated, follow the steps below:
- Open your Windows ESET product. If your product is not activated, your main window will be red:
[KB2792] Activate my ESET Windows home product using the license key
Issue
- "Product not activated" - Why does my protection status change color and what does each color mean?
- "Update information is not consistent"
- Invalid username and password
- Modules updates fail
- Product activation fails
- Enter License Key
Details
Your ESET home product is updated at least once a day with new virus detections and occasional program component upgrades. These updates will fail if your product has not been activated using a License Key.
Solution
- Click Help and support → Change license.
- Click Use a purchased License Key.
- Type or copy/paste your ESET-issued License Key into the License Key field and then click Continue. Make sure you enter the License Key exactly as it appears and include the hyphens. If you copy/paste be sure you don't accidentally select additional space around the text. Click here if you lost your License Key.
- Click Activate.
- Click Done. You have successfully activated your product.
