I had the same problem. Follow these steps:

Go to Device Manager. Inside "System Drivers" that is a Microsoft UAA
Bus Driver for High Definition Audio. Right click it and DISABLE. Right
click it again and UNINSTALL. Now you are able to start SETUP.exe and
install realtek driver.

This problems happens because windows added its own driver and it does
not allow realtek driver to complete its installation.
