Report flirc_util bug in GUI Bugs Posted October 10, 2021 Finally found a work-around. Apparently the first section of the command line is disregarded and not interpreted as a command if and only if it equals flirc_util.exe. I was using flirc_util <command>, not flirc_util.exe <command>. Everything works exactly as expected when including the .exe extension. Maybe this could eventually be adjusted to handle both cases (with and without the .exe extension)? Just a suggestion.
