snu5600 wifi usb stick

Helllo i am trying to connect to the internet with a wifi philips snb5600 card on a computer with windows 7, i plug it in pop in the cd and autorun starts i go through it bla bla then after installing it says please insert the usb stick so i do so then it says stick not found or something so i find this odd and plug it into all of my usb ports(one at a time) and no change. But i tried it on my other computer(with internet but through a lead) and i plug it in no cd or anything and a box comes up saying do u want to install the drivers from the *WEB* then i click yes then it installs and its fine so my problem is trying to install a usb wificard with no internet :/ so mabey theres drivers or something :/

comp that im trying to install card on is
windows 7

my other 1 is xp

apple
