Using Action with Win 8 compatibility mode and don't have any problems.

The Windows 8 driver for the Logitech lifecam Studio are not working with win 8.1.

You have to install the windows 7 driver on win 8.1 it's the only solution to get the MS Lifecam Studio to work with skype.

That is NOT true. I have all three webcams and no problem with Action on Win 8.1 64bit. My 10 year old Labtech webcam and my SJCAM, it's an Actioncam like gopro, are working too.There must be something wrong with your system or drivers.
