title: Silent install of chrome extension using registry
body: <p>For some reason I cannot get this to work. I'm following the exact procedure described here
  <a href="http://developer.chrome.com/extensions/external_extensions.html#registry" rel="nofollow">http://developer.chrome.com/extensions/external_extensions.html#registry</a></p>
  
  <p>And I still cannot get the extension listed. If I install it manually, using "Add Unpacked Extension" it works just fine.</p>
  
  <p>Any help would be greatly appreciated</p>
