Will not install unless you also install Google's automatic update engine for all of their software. It is described as a background process that monitors all Google update applications and updates them automatically.
I don't want this feature installed on my computer. However, Google gives no choice other than not installing any of their software. So thanks, but no thanks.
Not any different to installing safari or itunes on windows or office on mac. This is a growing trend for software releases that i see as becomming a problem if not kept in check.
