Priviledges to create COM components? What

I have a sound distortion problem and have tried to install the latest Realtek AC'97 driver download but installshield stops saying I do not have the priviledges to create the COM components. What are they and how do I check or amend. Is there some other way to install to overcome the audio problem or solve it another way?
