It looks like you've downloaded and tried to run the firmware update file - not drivers.
If you're using Mac OS 10.10 (Yosemite) or newer, please use this driver.
If you're using Mac OS 10.9 or earlier, please use this driver.
If you happen to be using 10.13 (High Sierra), you'll need to also disable the driver security here after installing the drivers once, then install them again.
