If you try to install Google Chrome behind a corporate firewall, the Google Chrome Installer may get stuck at the initializing step because it can't access the necessary components to download. There is an official standalone version of the Google Chrome installer (some may call it an offline or direct installer). If you're having trouble installing from http://www.google.com/chrome, check out the link below to try this alternate installer:
