Originally posted by Not a Number If you are using a Windows PC do you have a "thumb" drive, and SD card reader or other removable USB drive? If not connect your K-1 to your computer with a USB cable. Otherwise connect the USB/flash drive or card and in Windows Explorer right click on the drive and pick rename. Change the drive/volume name to S-SW140 and then you can run the file you downloaded from Ricoh.
If you are using Window 8.1 or 10 the update file complains it can't find a previous version but if you click OK - next - next - you can continue to install it without renaming a disk as above.
Thanks, and that worked...
