In order to use the product you need an activation key. Offline activation is not available since Update Downloader can't operate without Internet connection.
To activate your installation go to the Settings > License menu in the Web Management Console. If you have no valid license, you will only see your installation's Deployment ID. You will also see a warning in the Web Management Console header.
Press the ACTIVATE button to bring up the Activation menu
Type in your activation key
Press the SEND button
After successful activation the product will start downloading the latest available scan engines and malware databases. You can follow the status of the scan engine installation on the Inventory > Engines page.
When your hardware information changes, for example your mac address changes because the product runs in a virtual machine, the license get automatically reactivated on the first update attempt.
