I am running Windows 8.1 Pro with Hyper-V enabled. When I had Windows 8 I could install a Virtual switch with out any problems, since upgrading I can not install a Virtual Switch with External or Internal settings.
Not sure if this is relevant or not but when I look at the Ethernet properties never "Hyper-V Extensible Virtual Switch" or "Microsoft Network Adapter Multiplexor Protocol" are ticked. I have tried ticking them but get the error message "Could not add the requested feature. The error is: The data is invalid". I have checked that I am using the latest and correct driver for the card.
Any help gratefully received.
