So I am using this but for some reason it launches the same client twice

cd "C:\Program Files (x86)\Turbine\Dungeons & Dragons Online"
start TurbineLauncher.exe
cd "g:\Program Files (x86)\Turbine\Dungeons & Dragons Online"
start TurbineLauncher.exe

It launches the one in C twice which still works but then I have the C graphics settings instead of the G which I want set at low to keep resource use down. Can anyone figure out what the issue is? Or does anyone have a .bat file that will launch Shortcuts?
