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, where you should choose from the available modes:
Online: the product will contact the OPSWAT license server online, and acquire its license based on your Activation key and Deployment ID.
Offline: you can upload a manually acquired license file.
Request trial key online: if you want to try out the product first, you can receive a trial Activation key via email.
If you selected the Request trial key online option then follow the on-screen instructions.
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 scan engines are installed you can start using the installed Metadefender Core to scan files with multiple anti-malware engines.
For more information on how to scan files with Metadefender Core see Scan Files with Metadefender Core
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.
