HAXM Installation Failed message while installing Android studio :

The Android Studio Installs Intel HAXM when you install Android Studio. But you may get the HAXM Installation Failed message because of the following reasons :
1.) Android emulator is already running
2.)The processor is not Intel-based
3.)Unsupported OS
4.)Hyper-V Manager must be disabled
5.)Virtualization must be enabled in Bios ( VT-x )
6.)The PC must support Virtualisation
7.)Antivirus (Avast) may interfere with HAXM Installation

While starting Android studio shows “HAXM is not installed on this machine ” so you can install like mentioned below :

Open SDK Manager and download Intel x86 Emulator Accelerator (HAXM installer) if you have not.

Option 1: Go to Android SDK Folder –> Extra –> Intel and double click on HAXM installer and install it manually.
Option 2: If you do not have latest version of HAXM then you can open sdk manager in android studio and download it. Go to Android SDK Manager (Tools -> SDK Manager) and select SDK Tools. You will find the Intel x86 Emulator Accelerator HAXM installer listed here. Select it and click on OK.

In my case,i got the HAXM Installation Failed error as follows :

Fix:
Disable the Hyper-V Manager did the trick for me.

Hyper-V is another Virtualisation technique just like Intel HAXM. You cannot use both at the same time. Hence, It is necessary to Disable Hyper-V. You can follow these steps to disable Hyper-V

  1. Go to Control Panel -> Programs and Features -> Turn Windows features on or off
  2. From the window disable Hyper-V options
  3. Reboot your machine

Disabling the HyperV fixed the HAXM Installation Failed issue for me.
