Download the basic launchpad here:
http://launchpad.station.sony.com/
Make a shortcut or from the run prompt add the switch:
/game:eq2
(eg.
"C:\Program Files\Sony\Station\Launchpad\Launchpad.exe" /game:EQ2 Include the quotes)
You will need to use that switch everytime you want to patch as installing with this method will not create a EQ2.exe file, only EverQuest2.exe which can be used to bypass the patcher.
It's a long download, but it works.
