The Titanium Client can be purchased, or if you already own it, it can be downloaded legally from the internet via a number of different methods.
We recommend a fresh install of Titanium to ensure you have all the files necessary. EQLite and some of the other distributions floating around the EQEmu community do not have all the files required.
You will need to remove or rename the following files in your Everquest folder:
We recommend using LavishSoft's WinEQ2. If not using WinEQ2, you will need to create a proper shortcut to load the Titanium client. Find eqgame.exe in your Everquest directory, create a shortcut, then right-click the shortcut and select Properties and edit the Target field to include " patchme" at the end (without the quotes).
