Thank you for your reply. internet here has been minimal today, the phone company working on the cabinet.
Binary data makes sense of course, Chinese characters distracted me normally see graphics characters. I am logged on as administrator. The location is C:program files/go/bin. I also tried C:/go/bin, to take it out of the protected windows folders incase it cant write the output file. The key file is 388 bytes long.
I am getting a different message now. I also changed the scope type in rgtool.go to DHO1074. I also tried adding a dot to make "rgtool.go."
