I am using the free Hyper-V 2012 R2. I am trying to add RemoteFX 3D Video Adapter to one of my VMs. I have installed a dedicated GPU for this. However when I go to "add hardware" I get the error: "Hyper-V cannot add a RemoteFX 3D video adapter to this machine because the Remote Desktop Virtualization Host role service is not installed. Install the role service and then try again."
