PHP on Vista

I installed it like I always do yet it gives me an error so, i tried to go around it… but yea kinda not working on my end.

PHP Fatal error: require_once()[function.require]: Failed opening
required ‘SAM/php_sam.php’ (include_path=’.;C:php5pear’) in
sam_factory on line 1

yea… this makes me feel very dumb as i see people ask this question all the time and they somehow figure it all out… is there a different installer i have to use for vista, i prsume so and i’m just overlooking it/cant find it. I want to/would pefer to use apache.

(that or explain how to share internet between two computers with only 1 ethernet slot in my dorm (i have ethernet cables and some cat5 ends laying around so i can splice wires and stuff… its just that the network is very secure in… but i’ll explain that if i can’t get it to work on vista))
