Install class

[Balazs]

I have the problem that I wrote a simple dll and I would
like to call it from MSIScript with InstallUtilLib's
ManagedInstall function.
I do everything how the msdn says but somewhere I go
wrong.
In the logfile there is no help for me.

Has anyone any suggestion?
My C# code:

using System;
using System.IO;
using System.ComponentModel;
namespace TesMessage
{
[RunInstaller(true)]
public class MyInstaller :
System.Configuration.Install.Installer
{
public MyInstaller():base(){}

public override void Install
(System.Collections.IDictionary stateSaver)
{
base.Install (stateSaver);
string text =
this.Context.Parameters["text"];
ShowMessage(text);
}

protected void ShowMessage(string text)
{
Console.WriteLine( "The Install
method has been called with text, {0}",text );

TextWriter tw = File.CreateText
(@"c:\success.txt");
tw.Write(text);
tw.Close();
}

protected override void Dispose(bool
disposing)
{
base.Dispose (disposing);
}
}
}
