I'm having trouble with the USB writer tool and get these weird error messages: Error 1117 + a lot of asian characters, followed by some things that maybe relate to some windows functions. I am using Win 7x64. I've formatted the SD card to be one big fat32 partition, previously had my Raspian installation on it and working.
I also tried using the old method with Rufus, which for some reason also produces write errors. I just have no idea why. Both programs try to make new partions on the SD, that sometimes works and sometimes doesn't.
I've tried other USB-ports for the card-reader, rebooted the system between formatting and write attempts and am honestly out of ideas what goes wrong. Especially since that error message is sooo helpful
