HAXM installation fails claiming VT-X not present

Question

I\'m having difficulties trying to install HAXM for my emulator in Android Studio. I have an hp2000 notebook; I updated Windows 8.1 to Windows 8.1 Pro to activate the Hyper-V fe

Answer 1

For Windows 10, first of all install the intelhaxm-android.exe located in this folder: SDK\extras\Intel\Hardware_Accelerated_Execution_Manager. If it gives error during installation then try these solutions.

1. First all enable the virtualization from BIOS setting. To enable this restart the computer, when the computer starts then press ESC. Then select the F2 if the manufacturer is Dell.

2. 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 Intels website.

3. Check that hyper-v is disabled. To disable it go to the Control Panel then select the Programs --> Program and Features--> Turn windows Feature on or off (located on left side). Then find the HYPER-V. Uncheck the check box and restart the computer and try to install the hxm again.

4. Go to properties of "This PC" by right clicking on it then select the Advance System Settings (located on left side) then in Advance (tab) under performance click the Setting button. Then select the Data Execution Prevention (tab), then select this option turn on the DEP for all programs and services except those I select and restart the computer, and try to install the hxm.

Solution no 3 worked for me.

Answer 2

After enabling the virtulization in-bios do hard restarting via power button solved my problem:). I read in intel blog to do so. So try this option it may help:)

Answer 3

This procedure worked perfectly for me. Hope this helps.

1. F10 (Computer Set Up) - BIOS - Security -System Security -Enter - Virtual Technology (VTX)-Enable-FileSave and Exit
2. Goto sdk Folder: F:\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager Run intelhaxm-android.exe
3. You should be seeing a dialog box which quotes, "Completed Intel Hardware Accelerated Execution Manager Set Up Wizard. Click the Finish Button to exit the wizard"

Once this works, open android studio, and try running the emulator. You should be seeing "HAX is working and emulator runs in fast virt mode"

Answer 4

You can enable Intel Virtualization Technology from BIOS or if you dont have installed Emulator Acceleator(HAXM) you should install.

Answer 5

You must have an Intel processor that supports virutalization and ND bit on. You can check http://ark.intel.com to tell.
to set ND bit you can use bcdedit /set nx AlwaysOn
to set virtualization properly once enabled in BIOS you can type
bcdedit /set hypervisorlaunchtype off
If you're using Avast
disable "Enable hardware-assisted virtualization" under Settings > Troubleshooting)
