HAXM says Hyper-V is enabled when Windows says it is not

[SqlBenjamin]

I continually get an error when trying to install haxm that says:
"This computer does not support Intel Virtualization Technology (VT-x) or it is being exclusively used by Hyper-V."
When I run "emulator-check.exe accel hyper-v" in a command prompt I get the following:

---

accel:
0
HAXM is not installed, but Windows Hypervisor Platform is available.
accel
hyper-v:
2
Hyper-V is enabled
Hyper-V

---

However, Windows shows that it is not enabled:

I've even made sure the services were not running and they aren't.
I've double, no triple, checked that virturalization is enabled in the BIOS - it is. I've not only restarted but cut power to the machine for a bit too.
I'm running a Lenovo Yoga X1. The processor is an Intel Core i7 6600U.
I'm running it on Windows 10 Enterprise version 1803, build 17134.228. x64
This is happening with version 7.3 of haxm.

I'm seriously at a loss as to what to do in order to install haxm. All the forums say to do the same thing which I've already done to no avail. Is it that the check incorrectly detects Hyper-V being enabled? Do I need to uninstall a specific KB?

[raphaelning]

Thanks for the detailed description of the issue. It's similar to one I resolved before: https://issuetracker.google.com/issues/110260335#comment6

The gist of that post is:

Basically, Hyper-V could still be running despite what Turn Windows features on and off reports. To completely turn it off, you will need to disable a Windows Defender feature called HVCI through Windows Defender settings > Device security > Core isolation details > Memory integrity > Off (see attached screenshot). A reboot is required for this change to take effect.

[SqlBenjamin]

Thanks for the reply. I just checked that and it was already off. Unfortunately, I turned it on while thinking "I'll just make sure it's off by seeing if it turns on". (facepalm). Now I have to restart and turn it back off and restart again. :) Could there be something else preventing it or causing it to think it's on?

[raphaelning]

Sorry for the very late reply. This is one of the posts I missed during my time off...

Besides HVCI, I'm not aware of anything else that can prevent Hyper-V from being turned off. One last try: there's a CLI way to disable Hyper-V, and it may work more reliably than the GUI way (Windows Features dialog).

1. Open an elevated (i.e. Run as administrator) Command Prompt.
2. bcdedit /set hypervisorlaunchtype off
3. Also make sure HVCI (Windows Defender's memory integrity setting) is off.
4. Reboot.

You can prepare Windows host with Device Guard and Credential Guard hardware readiness tool on https://www.microsoft.com/en-us/download/details.aspx?id=53337
DG_Readiness_Tool_v3.6.ps1 -disable

[joshuamataaraya]

I'm also not been able to install HAXM.

Hyper-V is already off

My processor is Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz, 2801 Mhz, 2 Core(s), 4 Logical Processor(s) and based on their specification it supports Intel Virtualization Technology.
I can't access the core isolation setting as the device security option is not shown in my Windows Defender Security Center Menu

[raphaelning]

@joshuamataaraya Your CPU definitely supports VT-x. Have you checked whether VT-x is enabled in your BIOS? If you launch the System Information tool from Start menu, it should report whether VT-x is enabled in BIOS:

Hyper-V - Virtualization Enabled in Firmware Yes

You can actually copy the entire System Summary and paste it here, because it also gives us details about your Windows installation. Of course, please feel free to redact irrelevant/personal information.

[jkk88]

I'm also not been able to install HAXM.

You need to use Device Guard and Credential Guard hardware readiness tool as I wrote in previous post.

[joshuamataaraya]

Thanks @raphaelning and @jkk88 I've used the Device Guard and Credential Guard hardware readiness tool and it's working now

[raphaelning]

Great! Thanks @jkk88 for pointing us to the Device Guard readiness tool. I'm closing this issue now, but if @SqlBenjamin still can't get Hyper-V completely turned off after using the new tool, we can reopen the issue.

[impactx]

Hyper-V isn't showing up for me . I already enabled VT in bios and tried a bunch of things.

[HaHoYou]

So do you mean you already tried Device Guard readiness tool, disable it?

[HaHoYou]

What is your output of these command: `

bcdedit /v
sc query intelhaxm
powershell dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Ready`

[ghost]

I did pretty much everything mentioned above. But I still get the same error. I am trying to download haxm for androidstudio. I cannot continue without intelhaxm. Things I've done are mentioned below.

This is processor specs.

Hyper-v is already disabled from features and in command.

I've used the Device Guard and Credential Guard hardware readiness tool as well.

Virtualization is enabled when I check through task manager. But I cannot access enabling virtualization through BIOS setting because it does not show up.

Working for a solution for 5 days but still no progress. I disabled the antivirus program as well. I guess I do something wrong or missing sth important. Is there any other issues that can prevent downloading haxm ?
Helps are appreciated. Thanks.

[Nittu88]

I found some kind of trick that worked for me!
Hope it will help you solve your problems too.
At first I enabled Virtualization in the BIOS settings, but when I started Android emulation via Android Studio it failed to use hardware acceleration.
I followed the instructions here:

Open an elevated (i.e. Run as administrator) Command Prompt.
bcdedit /set hypervisorlaunchtype off
Also make sure HVCI (Windows Defender's memory integrity setting) is off.
Reboot.

but it didn't work.

Then I read the suggestion here:

and my tick has been disabled all the time.

I enabled it and restarted.
When Windows restarted i ran Android Studio again, just to check it was sending the same error on screen and I got struck seeing that, instead, it was working!!!

So, what worked for me was:

1. Running the command in the Command Prompt as Administrator
2. Enable virtualization in the BIOS
3. Check the following ticks were off
   
4. Enable this option here that was always disabled:
   

Don't ask me why but now it works properly.

[Nittu88]

Also, I uninstalled intel HAXM in Android Studio in "tools>SDK manager>SDK tools>Intel x86 Emulator Accelerator.
If I try to reinstall it I get the same error as before, but at least now I can Virtualize Android...

[jkk88]

Would be nice to change that misleading error message above (Ensure Hyper-V is disabled in Windows Feature), because there are more features they need to be turned off. MS article about disabling Device Guard or Credential Guard is here: https://docs.microsoft.com/en-us/windows/security/identity-protection/credential-guard/credential-guard-manage.

Thanks,
I followed the instructions and it worked for me.

[candice-dick]

My laptop runs on AMD and I have followed all instructions above and I am still unable to run the emulator. Please assist, thanks

[MagicAndre1981]

@candice-dick for AMD based system use Hyper-V platform, HAXM is Intel only.

[ghost]

Just came across this today. After 1903 update, Windows Sandbox has to be also turned off in Windows features. This fixed the problem for me.

[MagicAndre1981]

@fakeinc also use Hyper-V platform instead

[cihangocmen]

bcdedit /set hypervisorlaunchtype off this code worked.

[Omar2002]

its help for me https://docs.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/troubleshooting?pivots=windows
Disabling Device Guard solved this problem.

[bakeyevrus]

A combination of bcdedit /set hypervisorlaunchtype off and disabling Windows Hypervisor Platform in Windows Features worked for me.

[sampalmer]

To elaborate on @MagicAndre1981's suggestion of using Hyper-V instead of HAXM, Google recently added Hyper-V support to the official Android emulator. So instead of disabling OS security features to get HAXM working, some users can use Hyper-V by opening "Windows Features" and turning on both "Hyper-V" and "Windows Hypervisor Platform".

[nikolayAleksandrov]

I had the same issue and guess what once I enabled Hyper-V the problem had been solved. And yes also the message was to disable this feature as recommendation

[zjffun]

I also meet this problem and tried above solutions, but still can't install.
Then I tried close WSL function and then install successfully.

[DoubleBullet]

For you guys who still have not found the solution to disabling Hyper-v in any of the methods above, I have found another solution.

I would advise people to first try the solutions above, but if you tried everything then do this.
Go to Task Manager, and click on the Services tab. Disable all of the Hyper-V services (Anything usually with "Hyper V" or "HV".



This just stops the processes and can only be brought back manually if triggered. You can fully disable the Hyper V services if you click on the Open Services tab on the bottom of the task manager.

Once you done that.
Try to restart your computer and see if it works. If it still hasn't worked, then look in your services or processes to see if you missed any running services that are in the background.

[wcwang]

Thanks for your reply. The complete solution had been provided in the section One-time setup of this manual. It is suggested to follow the steps to disable Hyper-V thoroughly.

[weitzhandler]

I think there should be an official troubleshooting page that represents an organized checklist of things to do when facing this error.
I'm already spending this over an hour and that nasty error message is still on.

[weitzhandler]

Finally. This solved my issue.
The problem was, in Windows Features you also have to switch off Windows Hypervisor Platform.

Sorry for the very late reply. This is one of the posts I missed during my time off...

Besides HVCI, I'm not aware of anything else that can prevent Hyper-V from being turned off. One last try: there's a CLI way to disable Hyper-V, and it may work more reliably than the GUI way (Windows Features dialog).

thanks that did the trick for me

Thanks for your reply. Glad to know you have resolved your issue.

Wow really thanks this trick worked for me too 😃

[furier]

• CPU: Intel i7-7700K
• BIOS: Virtualization enabled, did previously run docker with Hyper-V just fine
• Hyper-V: Disabled

I found another way to solve this issue. Disable virtualization from BIOS and reboot. Install HAXM independantly, it will give warning that Virtualization is disabled, and the installer will roll back the installation. Go to BIOS and again enable Virtualization, and then reboot and install HAXM. It's done!

[fakhravari]

I have to use this command when I bring up Mac
bcdedit /set hypervisorlaunchtype off

But mobile simulator must be ordered
bcdedit /set hypervisorlaunchtype auto

What exactly should be done to run both at the same time?

[dimitar-nikovski]

If people are still experiencing this after trying the above hit & miss solutions, this issue should be reopened.

[demberto]

Also disable Windows Sandbox, I have an off topic question - will HAXM improve Gameloop (Android emulator, probably customized for gaming)?

Finally! This command and reboot did the job. This AVD tool is pretty terrible for compatibility.

For me I had to uncheck Windows Hypervisor Plateform as well:

Had the same issues, tried all solutions here.
Disabling all the Hyper-V services and rebooting worked for me! 🙏🏽

[L96Github]

Update: I tracked the issue down to having the "Isolated Browsing" setting enabled in Windows Security. It uses Application Guard which uses Hyper-V under the hood (even tough Hyper-V is disabled in windows features.

So, if you still have this issue be sure to check that "Windows Defender Application Guard", "Hyper-V" and "Windows Hypervisor Platform" are all disabled in the Windows Features window.

You beauty man , this worked instantly very well .. i have been looking for this solution for couple of days Thanks alot <3

[fisforfaheem]

weird issues...this should be fixed by google

[skull-squadron]

Encountered this issue and wasted 30 minutes on it.

The installer should mention HVCI needs to be disabled.
