QProcess啟動不了外部程序的問題

    QProcess* process = new QProcess(this);
    process->start("E:/bin/Release/temp/test.exe");   //無法啟動
    QString path = "E:/bin/Release/temp/test.exe";
    process->start(path);   //無法啟動
    process->startDetached(path);   //可以啟動
    QProcess::startDetached(path, QStringList(path));   //可以啟動

    //當程序路徑中含有空格的時候，僅設置程序路徑program是無法啟動的。還需將程序路徑傳遞給參數arguments。
    QString path = "E:/bin/Release/temp/test v1_0_0.exe";
    process->start(path);   //無法啟動
    process->startDetached(path);   //無法啟動
    process->startDetached(path, QStringList(path));   //可以啟動
    QProcess::startDetached(path, QStringList(path));   //可以啟動


    process->setProgram("E:/bin/Release/temp/test.exe");
    process->setArguments(QStringList("E:/bin/Release/temp/test.exe"));
    process->start();   //無法啟動

貌似start都不能啟動，很奇怪。。。
