hi, irolands here, newbie, need help installing vista, i'm upgrading from xp, in the install it gives me the option of installing without entering product key so i click "no" then it just goes back to wanting me to enter the key. what am i doing wrong? i have also lost the key from the packaging, where in the vista iso file do i find where the key might be hidden so i could find it with a key-finder program?
