Google has gotten in the bad habit lately of requiring you to install Google Updater to download any of its desktop apps, but if you're not keen on the required Updater install (and want to try Chrome), try the Google Chrome Standalone installer.
It downloads a full offline installation package for Chrome. The downside: It won't automatically update when Google Updater pushes out new versions of Chrome. But don't worry, we'll keep you updated
