I can not open my emulator in android studio that i have created. i install lollipop platform in SDK and create same api level emulator. see the error log in bellow image. i have set 512 ram for virtual device.
The Android emulator requires the Windows Hypervisor Platform (WHPX). Ensure WHPX is properly installed and usable.
