How do I get Google Chrome to launch?

[Rachel]

Google Chrome won't launch on my computer. Google says to disable firewall and see if it starts. I did that, still won't start. So I decided I was going to uninstall and then reinstall google chrome. When I go to uninstall it says to please close all google chrome windows. There are no google chrome windows open on my computer. So I opened task manager to see if I could close my "google chrome windows" from there. There are none. I even x-ed out of the internet explorer window to see if that was what it was talking about. Still won't uninstall. Help!
