Error on windows vista using outlook 2007 mail box setup

Hi, I have just installed outlook 2007 on my vista home PC but unable to configure my gmail account. tried all stuff from the web but no luck. I am sure there is nothing to do with email settings I am entering as using same I am able to setup email on other systems with similar office. Any help would be highly appreciated! Thanks in advance!
