Cd/dvd Emulation Software

I have just copied Harry Potter and the prisoner of azkaban with CLONECD and when I go to run the game the following error comes up “CD/DVD EMULATION SOFTWARE HAS BEEN DETECTED. PLEASE DISABLE ALL CD/DVD EMULATION SOFTWARE AND RE START THE GAME”.

I am new to this, so any advise would be great and yes I do own the game.
