System.IO.FileNotFoundException. Where do I find what path is wrong?

Question

I create small Windows Forms progs in VisualStudio2010, just for hobby. After releasing them I use the .exe file to run them on other PCs, without having to do any installation. Those PCs run Windows OS(7,vista,XP). The PC which I wrote the code had Win XP and the progs managed to work fine anytime.

Now I wrote another prog, on another PC, which runs Win 8.1 and I get the following error whenever I try to run the released .exe at other platforms, as mentioned above.

How can I locate what file is missing? tyvm

Answer 1

Problem solved.I had to modify my main,IOT to catch that exception and see what
was actually missing.

 static void Main()

{

 Application.EnableVisualStyles();
 Application.SetCompatibleTextRenderingDefault(false);
 Application.ThreadException += new  

ThreadExceptionEventHandler(Application_ThreadException);
      AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

  Application.Run(new Form1());

}

static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
{
  MessageBox.Show(e.Exception.Message, "Unhandled Thread Exception");
  // here you can log the exception ...
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
  MessageBox.Show((e.ExceptionObject as Exception).Message, "Unhandled UI Exception");


     // here you can log the exception 

}

Then I could see that the problem existed because Visual Basic Powerpack needed to be installed.I assume that machines without VS2010 installed,even if they have .NET 4.5, do not have that. The question is though, what was the difference this time and that package was needed IOT run the application.... The solution was found here actually, I need to say that. http://www.csharp-examples.net/catching-unhandled-exceptions/
