Make sure you have removed all the previously installed Apache,MySQL and PHP.
Some people suggest putting the my.ini or my.cnf into the windows folder ( bad idea ) So search for any my.ini or my.cnf that does not exists within the \wamp\.... folder structure and delete them.
Make sure you dont have the old Apache or MySQL services running. WAMPServer calls these 2 services 'wampapache' and 'wampmysql', so if you see a service called 'Apache' or 'MYSQL' running you must delete those old services. See the SC command for how to delete a service.
