I have Realtek AC'97 Audio built into my ASUS A8N-SLI Premium motherboard running on Vista Home Premium x64. The drivers I have downloaded from the ASUS website, from the Realtek website, whether the new or older versions fail to install! Vista gives me an error saying "cannot verify the publisher of the driver, " providing me with either the option to install anyway, or not. Despite clicking INSTALL ANYWAY, Vista hangs for a second, then comes up with the same message, same options... I have attempted trying to wait it out, thinking multiple .dll's are being installed, and Vista needs verification for each one, to no avail. I have tried using the boot option to disable driver signing, as well as installing in safe mode. Neither have worked. I would greatly appreciate any help, as I have not been able to find a solution, and not having sound is kind of killing my Vista experience!
