QProcess can not find the file specified

Question

I want to start a QProcess to execute an .exe file in the working directory with some arguments. The error string says that the specified file is not found indeed the executable is already in the working directory.

The output of the process under Win10 is:

workingDirectory: "\"C:\\devApp\\Build\\tmp\""
program: "dcmodify.exe"
arguments: (" -q", " -ie", " -gin", " -nb", " -ma", " (0010,0010)=na", " *.dcm")
error: "Process failed to start: system can not find the file specified."

If I execute same commands on the cmd I have no problems, such:

cd /d "C:\\devApp\\Build\\Tmp\" && dcmodify.exe -q -ie -gin -nb -ma (0010,0010)=na *.dcm

This is my code

QString workingDirectory =
  QDir::toNativeSeparators(QDir::cleanPath(Utilities::getAppPath() +
    QDir::separator() +
    toQString("Build") +
    QDir::separator() +
    toQString("tmp") +
    QDir::separator()));

QString executable = toQString("dcmodify.exe");

QStringList parameters;
parameters << 
toQString(" -q") <<
toQString(" -ie") <<
toQString(" -gin") <<
toQString(" -nb") <<
toQString(" -ma") <<
toQString(" (0010,0010)=na") <<
toQString(" *.dcm"); 

QProcess *proc = new QProcess(this);
  proc->setWorkingDirectory(workingDirectory);
  proc->setProgram(executable);
  proc->setArguments(parameters);
  proc->start();

  bool retval = false;
  while (retval = proc->waitForFinished());

  if (!retval) 
  {
    qDebug() << "workingDirectory:" << proc->workingDirectory();
    qDebug() << "program:" << proc->program();
    qDebug() << "arguments:" << proc->arguments();
    qDebug() << "error:" << proc->errorString();
  }
