The regular users who love chrome as their home always want to be with an updated notice like 'Google chrome is up to date.' But the problem is without proper installation of chrome there is another annoying notification comes "Update Server not available (error 3)".

As a tip, I would advice you to avoid FileHippo or any other 3rd party hosting site,and whenever possible go for the direct source of a program. Here are the official links for Google Chrome, Google Chrome Beta , Google Chrome Developer and Canary build:
