This will not be exactly the same but should be pritty close to what to do as I'm using ME to check this out:

Goto your game controllers panel
Then click Add
Then click Add Other rather then Custom
Then click have disk
Then click Browse
Then browse to the directory where you saved the drivers to
When you reach the directory, double click on the file that shows up in the left hand box
Now click ok
Now follow the install new hardware wizard.

See if that helps.
