Unzip the CDM file to a known location ( a folder like my documents or something that you can remember where to find it )
UNPLUG your computer from the internet physically.... this is the most common mistake when trying to update drivers..... windows thinks it knows what the smarty is and chooses the wrong stuff.
Once unplugged, plug in the smarty to a USB port and let windows recognize it.
Once it starts the update drivers deal choose advanced and select driver from a list, NOW Go find that folder from above and it should be one of the only drivers in there.
follow the rest of the instructions, don't listen to any of the windows warnings..... Microsoft is like the Dodge dealer....
Once completed, you will need schooled on the EXE file and updater
