QProcess is not working in WinXP , but it is working in all other machine...

I have used WMIC commad's in QProcess to fetch System Manufacturer and System Model name. Its working absolutely fine in Win Vista, Win 7 .But its not returning any value in Win XP ,

@

void CTestDlg::on_btnOk_clicked()
{
QStringList listResults = getProcResult("WMIC Path Win32_COMPUTERSYSTEM get Manufacturer,Model /FORMAT:list");
QString strData;

foreach( QString str , listResults)
    strData += str;

ui->textEdit->setText( strData);

}

QStringList CTestDlg::getProcResult(QString strCmd )
{
QProcess *process = new QProcess();
process->start( strCmd );
process.waitForFinished( 10000 );

//connect(process, SIGNAL(finished(int)), this, SLOT(commandFinished()));
 // Even i tried with SIGNAL(Finished) ..but no difference.

    QString sResult = QString( process.readAllStandardOutput() ).trimmed();
    if ( !sResult.isEmpty() )
        return sResult.split("\n");

return QStringList();

}

Please let me know whether i am doing anything wrong on this.

Check the exit and return codes of [[Doc:QProcess]].

Even i tried with all exitstatus, but no luck.

Finally i have used a batch file with WMIC command inside the batch file. now its working fine.
@
QProcess *process = new QProcess();
process->start( "executer.bat" ); // which contains WMIC Path Win32_COMPUTERSYSTEM get Manufacturer,Model /FORMAT:list

process->closeWriteChannel();

if( process->waitForFinished() )
{
    qDebug() << "Succeed: ";
    QString sResult = QString( process->readAllStandardOutput() ).trimmed();

    process->close();

    if( !sResult.isEmpty() )
        return sResult.split("\n");
}
else
{
    qDebug() << "Failed: " << process->errorString();
    process->close();

    return QStringList();
}
