Solution to “Your CPU do support VT-x”

How to solve the “Your CPU does not support VT-x” error.

I was not able to start existing Android emulator last week.
It happened after I ran a very old version of Android Studio alongside the current stable version.
As you would, I tried creating a new emulator.
I was presented with an error message below and not able to continue creating one.

I managed to solve this issue by doing the following steps.
  1. Go to Android SDK in Preferences
  1. Go to SDK Tools tab on the right pane
  1. Uncheck Android Emulator, hit the Apply button at the bottom
  1. Check Android Emulator, hit the OK button at the bottom
