Install Feature id 62 Snapshot Client

Hello, Im planning to add a hotadd server to make backup to VMware machines. But I need help to add the Feature id 62 Snapshot Client.  I need this because I dont have the following option to backup: Click Host Properties > Master Servers, double click the NetBackup master server, and click VMware Access Hosts. I have the NetBackup Enterprise Server but dont know how to add this feature.  Thanks
