Systems running Horizon Agent or Horizon Persona Management must meet certain hardware and software requirements. Requirements and Considerations for Horizon AgentThe Horizon Agent component (called View Agent in previous releases) assists with session management, single sign-on, device redirection, and other features. You must install Horizon Agent on all virtual machines, physical systems, and RDS hosts. Supported Operating Systems for Standalone Horizon Persona ManagementThe standalone Horizon Persona Management software provides persona management for standalone physical computers and virtual machines that do not have Horizon Agent installed. When users log in, their profiles are downloaded dynamically from a remote profile repository to their standalone systems. Remote Display Protocol and Software SupportRemote display protocols and software provide access to remote desktops and applications. The remote display protocol used depends on the type of client device, whether you are connecting to a remote desktop or a remote application, and how the administrator configures the desktop or application pool.
