fasterem: this how mine shows in My Documents after unzipping. D55IR-Moultrie update 692KB. 1) mine was the D55-IR and 2) after unzipping, I then sent the file to my SD card. I kept the unzipped file on the SD card. I just inserted the card in my computer and double clicked onit. When it opens, I have a folder named DCIM and beside it (looks like a sheet of paper with the right top corner folded over). This is named 135ISPFW Bin File 950 KB. Good luck.
