Not starting emulator in AVD (Android Virtual Device) Manager

After created an avd with Android Virutal Device Manger recently downloaded I couldn't start and launch an emulator. Nothing would be happened.
I figured out an solution as did it with a command line.
It said Bus error.

Here is a solution.
Rename a binary "emulator64-(avd's CPU/ABI)" found in /sdk/tools to "emulator", where old "emulator" may be renamed like "emulator.notused".
