PHP Installation Problem

Hi, I have installed PHP from using PHP 5.2.13 installer [20,929Kb] - 25 February 2010, and for some reason, the PHP folder did not show up on my Windows C:\ folder. When I tried to execute a PHP script from my IIS, it tells me HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.What could be wrong here?
