Locate the “USB_Drivers_w_64.zip” file that you just downloaded. Right-click the file and select Extract all and follow the prompts to extract the contents of the zip file to a folder.
Open the new folder that you extracted (the folder will also be called USB-Drivers_w_64 but will not have a zip icon) and open it. Double-click “PreInstaller” to run the USB driver installer. Let it scan your computer and install the new drivers.
Once it is successful you may plug your IFC back in (preferably to a different USB port than before) and wait for the blue light to come on.
