Sorry, I was wrong. I just tried downloading the firmware for the 16-55. It is zipped and the instruction is to unzip it. Once this is done there is a folder with the two files inside. The question is should you put the folder on the card or should you open the folder and just copy the two files on? The Fuji instructions do not help, so I guess try both. As the instructions on the Fuji download site does not mention opening the folder up, I would try putting the intact folder on first. unfortunately I don't have the 16-55, so I can't try it out.
