They are supported! You just need to switch the installer over to Windows7 compatibility mode.
FYI - that didn't work for me... what did was to disable driver signature enforcement
I am on Win8 64. All I did was run the compatibility trouble shooter. No problems. Recording Axe-FX via usb into reaper on my 27" acer touch screen. coooooooooool.

I recently installed windows 8, and basically I got the Fractal USB to half ass run, The fractal logo doesn't show up on my taskbar and the application won't open to see all those settings and what not. Also, it doesn't show up as ASIO anymore like it did in windows 7 for me. Now it runs off the MME/Direct X Driver as Axe Fx Line in.... Do it need to reinstall ASIO drivers or something?
I would uninstall then install in compatibility mode.
