To use Apex Central 2019, managed products (for example, Apex One, ScanMail for Microsoft Exchange) and other services, you need to obtain Activation Codes and activate the software or services. Included with the software is a Registration Key. Use that key to register your software online on the Trend Micro Customer Licensing Portal website and obtain an Activation Code.
When managed products register to Apex Central, the managed products add their Activation Codes to the managed product Activation Code list on the License Management screen. Administrators can add new Activation Codes to the list and redeploy renewed Activation Codes.
