have you ever had any mysql or different wamp package before? if yes, after uninstall it, did you perform a FULL clean up including in windows and in registry? if not, backup all critical data, then try to uninstall this wamp package, and before re-install this wamp, delete the whole wamp folder, search and delete all related files in windows and in registry including apache, mysql, php, wampapache, wampmysql, so on.
Have fun,
