I just had to uninstall HAXM and install it again. Then it started working again. Hope this helps someone!

Edit:

Oh wow, this was a long time ago. I have been using genymotion for a few months now, and never had any issues like that.

I think you are trying to run an emulator based on x86  I got the same error when I just download the HAXM under Extras category of Android SDK Manager  Actually  you need install it  Go to the directory of extras and run the installation of HAXM  Hope this will solve your problem

If you found    HAX is not working and emulator runs in emulation mode    problem while running android SDK  This mean your computer CPU must be intel core and must support    Hardware Accelerated Execution Manager     It means that you have configured the emulator in a way which is not supported by your operating system   See this link solving the problem http   www javaexperience com hax-is-not-working-and-emulator-runs-in-emulation-mode  ixzz2p3inMj34  Update   -  The link is down at the moment so posting archieved link of the webpage - https   web archive org web 20151024002104 http   www javaexperience com hax-is-not-working-and-emulator-runs-in-emulation-mode   If your CPU isn t intel  then you have to edit your AVD and choose  CPU ABI  as  ARM   For more details  please visit the link above

I had this error and the other fixes didn t help me  but changing the CPU type the emulator used did get it working    Create a new emulator and try using mips or arm for the cpu selection

I had the same problem  Just after enabling Internet Virtualization from BIOS  After that let the system boot and install HAXM once again  Now emulator will run faster than before and HAXM will work  Enjoy

I had the same problem recently    First you need to install HAXM in the Android SDK Manager  from the error message I think you already did that   This will enable the emulator to use the HAXM framework  and for this it needs to open the HAX device  On your system this cannot be found  hence the error message   To make this device available  you need to install the HAXM driver from Intel  You can find it here  http   software intel com en-us android articles intel-hardware-accelerated-execution-manager  You also need to enable virtualization in your computer BIOS    Hope this helps

The solution of Rohan will fix the problem as the error message will not be shown but the emulator will not use the hardware acceleration and thus be again very slow   I recommend instead to install the Intel Hardware Accelerated Execution Manager as described here   https   stackoverflow com a 10772162 891479
