You need to understand what is a OEM version it is used by software providers as a means to get an Autocad but with their software as the essential item. Refering to OEM document "Deliver products with scaled feature sets at scaled price points and provide an AutoCAD-based platform that cannot be customized or extended by end users." So any outside program lisp or .NET etc can not be ran by you. But you can add programs using the OEM key that is held by the software developer. You would have to go back to them to add. What program did you buy ?
