Note that after installing and starting the client for the first time, you can verify that your client is compatible with EQEmu by opening the dbg.txt file within your Everquest\Logs\ folder. The first line in that file will show the build date. That date must match one of the build dates listed below:

Titanium:
Starting EverQuest (Build Oct 31 2005 10:33:37)

Secrets of Faydwer:
Starting EverQuest (Built Sep 7 2007 09:11:49)

Seeds of Destruction:
Starting EverQuest (Built Dec 19 2008 15:22:49)

Underfoot:
Starting EverQuest (Built Jun 8 2010 16:44:32)

Rain of Fear:
Starting EverQuest (Built Dec 10 2012 17:35:44)


It is not required to check the build date, but this information is here as a reference in case there are issues getting connected after the installation is completed.
