ADI 198x Integrated Audio

I have the Dimesion 4700, recently I had the audio multimedia controller yellow flag that I see alot of people get. So it states that the drivers for this controller cannot be found. According to the forum I should download the ADI 198x Integrated Audio drivers but when i try to download them i receive the following error: (Installation could not be completed, the required file needed to complete download is missing) Please advise
