Originally posted by Mikesul I think this has already been said but just extract the file on your computer. Then put the bin file (and only the bin file) on the sd card. Be sure you put it in the root directory. If that is confusing reformat the card. When you open it to transfer the bin file you will be in the root of the card. The instructions on the Pentax web site are very easy to follow if you read them in sequence and carefully.
So I did transfer the .bin file to the root directory of the SD card. There was no .exe file, just a .zip compressed file which I extracted and got one .bin file . Then I put the card in the camera, pressed MENU while turning on the power, and all that happened was that I saw the window saying version 1.0, then the window went to displaying information about the current settings.
Any other ideas - or whom can I ask about this? Tech support for Adorama, where I bought the camera, does not give assistance in this situation.
