Why don't you uninstall them all and use xampp?
http://www.apachefriends.org.
It has Apache, PHP, mysql, Filezilla server, server stats and other applications and needs no installation. Execute mysql_start.exe and you're ready to run on localhost.
(well, there is a setup.bat, but I doubt it installs any dlls or any registry setting, but I dunno, it works great for hoem webserver)
