Can't install google chrome. may it need a windows service?

I’m on WinXp sp3. And ocasionally disabled some windows services to speed up the system; installed Google Chrome 3, and can’t update it. I run the google chrome last version and it just do nothing. at all. So i turned on the google update service. and some windows installer service on, but after turn on all these services its the same thing. Maybe google chrome needs some specific windows service to run correctly… does anybody know which one?
