Failing to start a new Qt program

[gabriel-1]

However, i am able to run my project directly from: /Users/user/projects/build-my_project-Desktop_Qt_5_6_3_clang_64bit2-Release/my_project.app/Contents/MacOS/my_project, using the terminal

I was able to run my project by renaming the file "QtProject" in the .config folder, so QtCreator could generate a new "QtProject" file.

The error "Failed to start program. Path or permissions wrong?" no longer occurred.

Maybe there was something wrong with the "QtProject" file, but I have no idea what it was.

gabriel-1, thanks to post your solution. It worked for me too. I was in the same situation of you, and now, thanks to your answer i can run/deploy my project. It curious that researching over internet, you are the only one that proposed the only solution that works. Thanks
