Failed to build bin file in CoIDE

Hi seppe,
Thanks for the quick answer.
I just tried 5.4 and 4.8 version and it still give me the same error. Before, I used 9 version.
I use your software, but its lightly changed by my former coworker to work with our external hardware, so I can’t use your example for SW. I know it was working earlier, and that he was using Coocox to create bin file. I just lost the bin file because of this former coworker mistake :(. But I have the right .coproj project.
Would it be hard for me to migrate this project from Coocox to SW? I never than something like this before
