Nu imi merge nici 2.63 imi apare install realtek hd audio driver failure (error code 0xE00000027)
Open Device Manager (Start> Control Panel> System> Hardware)
In the "View" menu manager, select "Devices by connection":
Disable and uninstall by right clicking on "Bus Driver for Microsoft UAA High Definition Audio",
You can now install the drivers normally and without error.
