kindly help me on licensing part

Hi All,

i have query on VMware V-RAY edition Licensing,i am going through the licesing guide of symantec.

symantec V-RAY Lic Includes the following 

1 backup Exec Server

Agent for application and db for unlimited VM 

deduplication option 

Agent for VM-WARE and Hyper-V,

according to that guide Agent For Window and Agent for Linux is included in Agent for VMWARE and Hyper-V but they also maintained the Agent for Window and Linux to be purchased saparetly,

kindly clear this, can i install the agent for window seperalty or Agent for VMware will give me the funcnality to Run Agent Assisted backup with out installing the Agent for window 

Or Do i need to pay for the Agent for window
