Question

I have a setup project with a custom installer class which launch the application at the end of the installation. In the setup, I create a shortcut to the output of the application. The installation goes fine. But when I click on the shortcut, the installer restart and the application launch at the same time? Why?

No, the code of my custom class is:

/// <summary>
/// Installer class to automatically launch the application at  the end of the installation/
/// </summary>
[RunInstaller(true)]
public partial class InstallerStartApplication : Installer
{
    /// <summary>
    /// Initializes a new instance of the <see cref="InstallerStartApplication"/> class.
    /// </summary>
    public InstallerStartApplication()
    {            
        InitializeComponent();            
    }

    /// <summary>
    /// Raises the <see cref="E:System.Configuration.Install.Installer.AfterInstall"/> event.
    /// </summary>
    /// <param name="savedState">An <see cref="T:System.Collections.IDictionary"/> that contains the state of the computer after all the installers contained in the <see cref="P:System.Configuration.Install.Installer.Installers"/> property have completed their installations.</param>
    protected override void OnAfterInstall(IDictionary savedState)
    {
        base.OnAfterInstall(savedState);


    }

    // Override the 'Install' method.
    public override void Install(IDictionary savedState)
    {
        base.Install(savedState);
    }

    // Override the 'Commit' method.
    public override void Commit(IDictionary savedState)
    {           
        base.Commit(savedState);

        try
        {
            Directory.SetCurrentDirectory(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));
            Process.Start(Path.Combine(Directory.GetCurrentDirectory(), "IERssNotificator.exe"), "-c");
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex);
        }  
    }

    // Override the 'Rollback' method.
    public override void Rollback(IDictionary savedState)
    {
        base.Rollback(savedState);
    }


}

I launch this at install and commit custom action.

ok, I found the problem. The error is in the code of the custom installer class:

Process.Start(Path.Combine(Directory.GetCurrentDirectory(), "IERssNotificator.exe"), "-c");

This launch a process, not asynchronous and the setup never end. It is why it always restart the setup.

I change my code and laucn the process into a separate thread and so the setup complete.
