I cannot install Realtek High Definition Audio drivers. Even when I try to install from CD that cam with the mptherboard or downloaded files from the website, the installation fails. Nowmally the installshield starts and then halts and then tells me that the Realtek High Definition Audio drive installation has failed and then it will close. I have already tried to uninstall the audio drivers from the device manager but it says that I do not have any audio drivers installed. I am on a Intel Desktop Board D945GCNL, can anyone please help me out. Thanks.
