Trouble installing Google chrome?

I faced a minor problem when installing Google chrome - even without any firewall running but connected to internet.Google installer failed, throwing the error no 0x80072efd- which means GoogleUpdate.exe could not connect to internet.

The solution, at least in my case, is to manually start zonealarm and then grant permission to googleupdate.exe when installing. (Earlier,I had disabled firewall from starting automatically on system startup). Without firewall, Google chrome should have installed easily,but seems to work only after firewall is started.Uh!
