Hello John,
I believe you have the Symantec Protection Suite Enterprise Edtion 3.0. If the Protections Suite that you have is an upgrade from Multi-tier protection, you may register the Upgrade Notification ID in yuor licensing Portal Account in order for you to get the license key for BESR for Desktop. If thats a new purchase license for Protection Suite, you just need to register the serial number in your Licensing Portal and it should generate a license key for BESR Desktop Edition.
