Getting Same Error message...
I'm having the same issue with Windows XP SP2, here is my profile setup which includes the parameters.
I saw in some older posts people saying you needed to download a Everquest2.exe file from somewhere? But I wasn't sure if it auto did that in the ISXEQ2.exe installer? when i run Everquest2.exe i get this error, but if I point it to Launcher.exe it doesnt error & I see inner space running..
