C# – Visual Studio Just In Time Debugger: An unhandled Microsoft .Net Framework exception occurred

I am trying to find the cause of the following error when I run my WPF application on Windows XP.

An unhandled Microsoft .NET Framework exception occurred in MyProgram.EXE [2672] Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time

Check the documentation index for 'Just-in-time debugging, errods' for more information.

I used to have VS2010 running on my XP box but I have uninstalled it.

How do I get more information about what is causing the error?

I am using .Net Framework 4.0 which is installed on the Windows XP machine.

The application runs correctly on Windows 7.

[Update]

The start up object is MyProgram.App

this contains

    public partial class App : Application
{

}

stepping through on the dev machine takes me to

public MainWindow()
        {
           // various controller set up commands
        }

on the dev machine I next step into

MainWindow_Loaded()

however it doesn't make it this far on the XP Machine.

[Update]

I was able to edit the procedure that set up the commands

private void WireupCommands()
        {

            AppDomain currentDomain = AppDomain.CurrentDomain;
            currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);

            this.CommandBindings.Add(new CommandBinding(MainCommands.AppExit, MainExitCmdExecuted, AlwaysCanExecute));  // etc
         }

static void MyHandler(object sender, UnhandledExceptionEventArgs args)
        {

            Exception e = (Exception)args.ExceptionObject;
            MessageBox.Show(string.Format("{0} {1}", e.Message, e.StackTrace));
         }

And this reported the error "Image Format Is UnRecognised" along with a stack trace that barely contained a line of my code.

A solution for this is documented here

I still get the Just In Time Debugger message after this
