I have an Alienware Area 51 running Windows 7 64-bit. I have two Di Novo keyboards and two MX Revolution mice. Everytime I try to install Setpoint 6.20 it says it is incompatible with my Alienware software. My mice work without the software but the keyboards are totally non-responsive. I submitted at support ticket to Logitech who was absolutely no help at all. Can anyone please suggest a workaround so I can use my keyboards again.
