#include <QApplication>
#include <QObject>
#include <QTableWidgetItem>
#include <QTableWidget>
#include <QTimer>
 
    int main(int argc, char *argv[])
    {
        QApplication app(argc, argv);
       QWidget *window = new QWidget;
      QWidget *window1 = new QWidget;
       QTimer *timer = new QTimer;
        Ui::Form1 ui;        
        Ui::Form ui1;
       ui.setupUi(window);
        ui1.setupUi(window1);
 
        window1->show();  
 
 
        QObject::connect(timer, SIGNAL(timeout()), window1, SLOT(hide()));
        timer->start(1000);	           
    QObject::connect(window1, SIGNAL(hide()), window, SLOT(show()));         
        return app.exec();
    }

The error says you have a permission problem. Check that you don't already have a release\new.exe file, and that if you do, it is not read-only.

Make sure that your application isn't running when you link a new version.
