It looks like the new versions of the Arduino installers have archived the Drivers into a zip file in the Drivers folder called Old_Arduino_Drivers.zip. We'll need to extract these so that Windows can see them in the folder.
To do so:
Use your Windows Explorer to open up the folder: C:\Program Files (x86)\Arduino\drivers . Right-mouse click on the Old_Arduino_Drivers.zip file and extract them in the same folder.
Then go back and repeat the same process you tried before. Windows should now be able to find the driver you were looking for.
