Still Not Working but I have done an uninstall and reinstall, then installed the relevant post processor.
Now the MillingPostExe_Paths.txt file exists and is in the folder at "Butch Elrod/AppData/Local/Temp". When trying to post (make gcode) I still get the error that it cannot find "Elrod/AppData/Local/Temp/MillingPostExe_Paths.txt" NOTE the lack of Butch at the start. Could the space in the user name be causing this error???
