Just a couple of points:
- You must register your VMware software on www.vmware..com/lisensemgmt site
- After registration you need to create and download both licenses: VI3 foundation edition and VI3 Consolidated Backup
- Open foundation license and consolidated backup license file with NOTEPAD and merge them in one file.
- From VMware Infrastructure Client - Configuration - Licensing Features: Point to the merged file as the Host License File.
- Under Add-Ons (Edit) check the box against Vmware Consolidated Backup.
