I get the typical HAX error. Win7 x64, i7-2630QM
emulator: Failed to open the HAX device!
emulator: Open HAX device failed
HAX is not working and emulator runs in emulation mode
The drivers are installed, virtualization is enabled in the BIOS, yet HAX still refuses to work. It used to work, but stopped after I reinstalled Windows. I believe, both Windows versions were the same, x64 Professional.
It sounds like when you reinstalled Windows, your HAXM drivers got blown away. Have you tried re installing them? If not, you should probably get the latest versions: http://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager
This question is pretty old - did you get it to work? I was wondering if the comment above helped?
