Error during installing HAXM, VT-X not working

I am an entry-level Android software developer. I recently heard about HAXM that support emulator in rendering graphics more smoothly. I downloaded appropriate file HAXM file for Windows 7 64 bit, unpacked and started installing. However, during the installation process I get this error:

"This computer meets requirements for HAXM, but VT-x is not turned on..."

I checked many forum about this problem, including checking the version of BIOS and enabling Virtual Technology on BIOS. I followed the steps posted in the following forum:

Intel HAXM installation error - This computer does not support Intel Virtualization Technology (VT-x)

However, I don't have any lines about Hyperlaunch and I could not find Hyper-V options in my Windows features. I don't have any idea how to solve this problem.

Solution 1:

Even if you have enabled the Virtualization(VT) in BIOS settings, some antivirus options prevent HAXM installation.

For example: In Avast antivirus under Settings (parametres) tab > Troubleshooting (depannage), you should uncheck "Enable Hardware-assisted Virtualization" ("activer l'assistance a la virtualisation").

Now restart your computer and re-install the Intel's HAXM which can be found under ~SDK_LOCATION\extras\intel\Hardware_Accelerated_Execution_Manager. You can also manually download the standalone HAXM installer from Intel's website.

Solution 2:

I had to enable it in my BIOS as shown below (for Asus):

Solution 3:

I had exactly the same problem. And this is how I could fix it.

Step 1: Turn virtualization on in BIOS settings.

Step 2: Control Panel -> "Programs" -> "Turn Windows features on or off" (under "Programs and Features") and locate "Hyper-V", uncheck, reboot.

Step 3: In Avast->Settings->Troubleshooting. Uncheck "Enable hardware-assisted virtualization" & "Enable avast self-defense module"

Final step and the main:
Go to MyPC / right click / Advanced System Settings / Advanced / In Performance click SETTINGS / Data Execution Prevention and enable DEP for all programs and services.

The last step helped me to solve this problem. Hope you too.

Solution 4:

I had the same issues on my notebook which runs Windows 8.1

Try this:

• Check if Hyper-V options in "Windows Features activate or deactivate" are deactivated
• Download and install the latest Oracle VirtualBox
• Reboot
• Install HAXM
• Reboot-->open BIOS--> Enable 'Execute Disable'

It looks like that the installation of VirtualBox sets a flag that "turns" VT-X on.
