title: Android studio first run stuck at "Downloading Components" window
body: <p>I have downloaded the latest android studio bundle from android site. Installation was successful, but when I run it for the first time, it shows a window in the screenshot with message "Downloading Android SDK Tools, revision 24.1.2" and then it hangs on infinitely. 
  When I click on cancel and then show details, the message in attached screenshot appears. This dialog never disappears even on clicking the close button. I have to end it from process manager.
  I was wondering if anyone has been able to make it work.
