The latest driver compatible with Z77 is 126.96.36.1999. It may be listed as a version as late as 188.8.131.523, but the driver itself is 184.108.40.2069. Drivers that are 11.1.*.* or later are not compatible with Z77.
I'm curious as to why your device is not showing. It might be showing under "Other Devices", but knowing Windows 10, it might be running it's own driver. Intel Chipset driver package also has it's own NULL driver it will use for ME if installed.
If you want, I can look at it through teamviewer as I am genuinely curious.
