Android : Why does my Emulator not work?

I am using Eclipse 4.4 and for some reason whenever I try to start an emulator I get the following errors:

Starting emulator for AVD 'doridX'
emulator: Failed to open the HAX device!
HAX is not working and emulator runs in emulation mode
emulator: Open HAX device failed

Does anyone know what causes this and how I can fix it? I have currently tried:

• Deleting the virtual device and recreating it.


• Closing Eclipse and restarting the programme.


• Closing all open emulators and try launching it again.


• Uninstalling all packages related that were installed on Eclipse and reinstalling them.

The settings for my AVD are:

• AVD name: droidX


• Device: Nexus 5 (4.95", 1080 x 1920: xxhdpi)


• Target: Android 4.4.2 - API Level 19

• Skin: No skin


• Front Camera: None


• Back Camera: None


• Memory Options: RAM: 768 VM Heap: 64

• Emulation Options: None
