Launcher.exe will NOT work for the first box -- where it asks for everquest2.exe. That is the actual game executable and will be present no matter what patcher you are using.
Where the EQ2MAP updater *will* accept Launcher.exe is the second one -- the one that normally points to EQ2.exe, which is the old-style launcher. That is where it needs to point to Launcher.exe if you're using that launcher and want it to open correctly from the EQ2MAP updater.
