@Agito Try a complete rebuild: delete build folder, run qmake, build.
Also: try to disable anti-virus software, maybe it is blocking the application.

@Agito
Also, not that it should affect that error message, but if you are going to want to run under debugger you might want to change your current configuration over to building debug version.

Agito

@jsulm I'm Tryed but not work

JonB

@Agito
Check that you are building to target x64. Try building for Debug anyway to see if same message.

@Agito

@Agito
This doesn't state whether recompiled for debug your program runs or still says "not in executable format".
