[psmukilan]

Can any one guide me how to launch the installed application immediatley after the Finished screen button clicked. Once the user clicks the finished screen "Close" button, i need to launch the installed application. I tried with installer class. Sample code is given below.I have created a class library and within that an installer class. I tried with the afterInstall event, but its not working.

namespace ClassLibrary1
{
[RunInstaller(true)]
public partial class Installer1 : Installer
{

public event InstallEventHandler AfterInstall;

public Installer1()
{
InitializeComponent();
AfterInstall += new InstallEventHandler(AfterInstallEventHandler);
}

private void AfterInstallEventHandler(object sender, InstallEventArgs e)
{
Process.Start(@"C:\Program Files\Surisoft\SampleSetup\SampleApplication.exe", "/q");
}
}
}

Is there any other way to reach this requirement. Please help me im strugling.
