      This command works fine from Windows 7/10 command shell:

      msiexec /passive /i "c:\test space.msi" TARGETDIR="c:\test space"

      But msiexec complains invalid arguments and pops a window of help messages when running via QProcess::startDetached.

      Here is the piece of code:

          QString target = "C:\\Test Space";
    QString msi_file = "C:\\test space.msi";
    QString msiexec = QStandardPaths::findExecutable("msiexec.exe");
    QStringList args;
    args <<"/passive"<<"/i"<<QDir::toNativeSeparators(msi_file);
    args <<"TARGETDIR=\""+QDir::toNativeSeparators(target)+"\"";

    if (!QProcess::startDetached(msiexec, args)) {
        qDebug()<<"Start msiexec failed!";
    }

      The full code is attached as main.cpp

      It works fine if remove the space from 'target' string.
