Right-click and choose “Run as Administrator” to run the file and the DDO Live server client should launch correctly.

CD "C:\Program Files\Turbine\DDO Unlimited"

C:>CD "C:\Program Files\Turbine\Dungeons & Dragons Online - Stormreach"
C:>CD "C:\Program Files\Turbine\DDO Unlimited"(If using Windows XP or Vista 64bit use one of these below instead):
CD “C:\Program Files (x86)\Turbine\Dungeons & Dragons Online – Stormreach”
