QProcess::start() cannot run a excute file while the QProcess::state() is QProcess::R

Hi there, I got a piece of code right down here:

fullPath = QString("E:/bin/fis/wave.exe"));
QProcess *process = new QProcess();
process->start(fullPath);
if(!process->waitForStarted())
{
   qDebug() << process->state();
}
qDebug() << "~" << process->state();

fullPath = QString("E:/bin/fis/wave.exe"));
QProcess *process = new QProcess();
process->start(fullPath);
if(!process->waitForStarted())
{
   qDebug() << process->state();
}
qDebug() << "~" << process->state();

To copy to clipboard, switch view to plain text mode 

The qDebug() output is:

~ 2

~ 2

To copy to clipboard, switch view to plain text mode 

It means running (QProcess::Running equals 2) ,but I cannot see any process called wave running on my computer through Task Manager, neither the GUI. Anybody has suggestions?
