When you said "even the simple program of HELLO WORLD is not working in MPLAB SIM". I don't know what kind of problem you are facing. Compiler problem? IDE problem? Simulation problem? or all the three problems?
I guest you have problem with setting up the IDE and setting Up Language Tools. If so, the following links will help you.
