1) Do not remove the downloaded version of Android Studio, leave it intact 2) Google is looking for an old version of Android Studio, in my case 2.1.1 3) Download and install, SELECT CUSTOMS INSTALLATION 4) A message should appear with a message about "Another version was found Android Studio, the installer will download only missing files "5) Confirm by starting a new project
