QProcess won't start executable on Windows

[Sucharek]

Hi, so I have a problem with QProcess, because it doesn't want to start an executable.
I've checked paths, tried multiple things, but nothing worked so far...
Here's what I have right now:

#include <QCoreApplication>
#include <QProcess>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QProcess startServer;
    startServer.setWorkingDirectory("C:/Users/janso/Desktop/more/WSL_GUI");
    startServer.start("cmd /C", QStringList("Window.xlaunch"));
    startServer.waitForFinished();
    qDebug() << startServer.readAll(); //prints ""
}

No output whatsoever.

@Sucharek said in QProcess won't start executable on Windows:

"cmd /C"

This is wrong - there is no command cmd /C, just a command cmd which takes /C as first argument.

/edit: and if Window.xlaunch is really a executable then there is no need to execute it through cmd at all - it should be started directly then instead.

Hi
You seem not to point to an exe for it to execute ?

what is Window.xlaunch ?

Hi @Christian-Ehrlicher, that solved it. Thank you :)
