title: Android Studio: "Update & Restart" doesn't work
body: <p>Every morning after start of Android Studio I became a dialog with information about new version of Android Studio (Beta). If I click on "Update &amp; Restart" the patch will be downloaded (I see the progress bar and the growing file size). After that the Android Studio will be restarted but... the update is not installed! I can repeat it if I click on "Help/Check for update".</p>
  
  <p>Has anybody an idea how to fix this?</p>
  
  <p>P.S. Sure it is possible to download the full version and install it manually, but it would be so convenient to use automatically updates.</p>
