I just installed the Windows 10 anniversary update and now I can't start my Android emulators.
Android Studio shows the following message.
Android Emulator is incompatible with Hyper-V
But as you can see in the following image, Hyper-V is disabled.
I already rebooted the machine. I also tried running the following command from an elevated command prompt:
bcdedit /set hypervisorlaunchtype off
No luck.
Tried launching the emulator from a command prompt fails with the following message:
emulator -avd Nexus_5_API_23
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: Please disable Hyper-V before using the Android Emulator. Start a command prompt as Administrator, run 'bcdedit /set hypervisorlaunchtype off', reboot.
Has anyone run into this issue?
The problem in my case is that I had Credential Guard and Virtualization Based Security.
I disabled the mentioned Windows 10 features using Device Guard and Credential Guard hardware readiness tool.
Unzip the tool, in a Powershell command go to the folder where you unzipped the tool and type:
DG_Readiness_Tool_v2.0.ps1 -Disable
After rebooting I was able to reinstall HAXM and start my emulators.
You can turn off Hyper-V in the services menu (type "Services" in the Search thingy), and also use the Services menu to turn it back on. Even though it may not be necessary I still reboot after doing it this way.
EDIT: And also did you run Command Prompt as Admin?
EDIT2: Reinstall Intel HAXM, as @Morrison_Chang says
