Sorry that isn't working.
That is the driver you need is all I can tell you.
Download the zip file from that link instead of the exe file.
Extract it to a folder.
Go to the device manager, and click on the smbus controller. Click on the driver tab.
Click on Update Driver. Select the Browse my computer for driver software and browse to the driver folder you unzipped.
Make sure the Include Subfolders box is checked and see if the driver installs that way.
