Hi and welcome:
Just to confirm, when you downloaded the file you expanded that out to a generate a file with a .FIR extension?
The recommended thing to do is to copy that .FIR file to a cleanly formatted SD card, insert that into the camera, turn it on and go to the appropriate option in the menu system. When you select to upgrade the camera should search for the FIR file in the ROOT directory of the SD card and will perform the firmware update.
cheers, TREVOR
