Workaround available Windows, Linux Updated November 13, 2026Based on 3 user reportsHow we research

Quick answer

Intel HAXM is no longer supported by the emulator. Enable Windows Hypervisor Platform (WHPX) on Windows, make sure virtualization is on in BIOS, and uninstall HAXM. AEHD is being sunset on December 31, 2026.

Most likely fix: Turn on virtualization in BIOS

How to fix it

Try these in order — the most common fix is first.

  1. 1. Turn on virtualization in BIOS

    1. Reboot and open BIOS/UEFI setup
    2. Enable Intel Virtualization Technology (VT-x) or AMD SVM Mode
    3. Save and boot into Windows

  2. 2. Enable Windows Hypervisor Platform (recommended)

    1. Start menu > search 'Turn Windows features on or off'
    2. Tick Windows Hypervisor Platform and click OK
    3. Restart the computer
    4. Run emulator -accel-check and look for 'WHPX ... is installed and usable'

  3. 3. Uninstall old HAXM

    1. In an admin command prompt run sc query intelhaxm to see if it exists
    2. In SDK Manager > SDK Tools untick Intel x86 Emulator Accelerator (HAXM installer) and apply, or remove it in Windows Settings > Apps > Installed apps
    3. If needed run sc stop intelhaxm then sc delete intelhaxm

  4. 4. If you use AEHD

    1. Install via SDK Manager > SDK Tools > Android Emulator hypervisor driver
    2. Check with sc query aehd; STATE 4 RUNNING is good
    3. Google says AEHD sunsets on December 31, 2026, so plan the switch to WHPX

  5. 5. Linux: set up KVM

    1. Run sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
    2. Run sudo kvm-ok to confirm acceleration can be used
    3. Make sure your user can access /dev/kvm

  • Intel HAXM removed from emulator 36.2 onward
  • Windows Hypervisor Platform feature not turned on
  • Hyper-V, Core Isolation or other tools conflicting with AEHD
  • Running the emulator inside another virtual machine (not supported)
