Did you install eq2 in that location the 1st time you installed it and then move it to drive D: later on?

If so open up your registry with regedit and braws to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\everquest2.exe

In there you will find local paths to everquest2 change them to reflect the new path.

You also may need to edit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\everquest 2.exe

I don't know if it reads info from here or not to deside where to put stuff, but worth trying I guess.

Also <%PROGRAMFILES%> is probably set to c:\Program Files
