created a simple windows service and a set up project for that .I uses 
Settings feature in .net 2.0.It has a windowsservice1.settings file with a 
user scope variable named “Settings1” with a default value “A”. 

In the custom installation file I change the value of the settings1 variable 
to  a new value “ZB” and saves it.In the start event of the service I write 
this value to a text file .But I get the old value “”A”.But this works with a 
windows application.

Do you have any ideas on this?

 

protected override void OnAfterInstall(System.Collections.IDictionary 
savedState)

        {

            System.Diagnostics.Debugger.Break();

            base.OnAfterInstall(savedState);

            global::WindowsService1.WindowsService1.Default.Setting1 = "ZB";

            global::WindowsService1.WindowsService1.Default.Save();

        }

 

 

 

protected override void OnStart(string[] args)

        {

            // TODO: Add code here to start your service.

         

           // System.Diagnostics.EventLog.WriteEntry("Application","started 
");

           System.IO.StreamWriter fs= 
System.IO.File.CreateText(@"C:\ser.txt");

           fs.Write(global::WindowsService1.WindowsService1.Default.Setting1);

           fs.Flush();

           fs.Close();

        }
