Try this:

QProcess *p= new QProcess(this);
p->start("yourotherapp.exe",QIODevice::ReadWrite);

Try this:

int exitCode = QProcess::execute(program);
qDebug("Exit code is: %d.", exitCode);

and check what happens. This is a sync call. After you understand what is happening, change it back to async if you need it.
