Today on Vista, it asked me to turn on the automatic updates and I scheduled it for 3.00 AM everyday.
After few minutes got a notification that I have updates and asked to go ahead with express install. After the install is done, it popped up a dialog telling the updates were unsuccessful for my SoundMAX integrated Digital Audio. But it did not display any other info why the installation was unsuccessful. Anyway, I clicked on OK and the Automatic Updates dialog disappeared.
But again after few minutes got the same notification back that I have some updates for my system, and up on clicking on either express or custom install, the same process continues with failed update to the same SoundMax Audio.
I do not know why the above update failed as it is not giving any more info, and even after the failure not sure why it is keep asking me that I have the same updates for the system.
