Failed to check for updates

Hi! My application is not managed to check for updates. I followed the Step-by-step walkthrough guide, created the simple application with Help menu and AutomaticUpdater. Application is written in C#, VS2012, NetFramework 3.5. The weUpdate.exe itself works perfectly, which means that there are no problems to download updates either from the network (http://) or from the locale machine (file:///) (I tried both variants). IIS server is configured. I could not find solution here in the forum. How can I check what is the problem? Is there possibility to get some myUpdate log information? Please help!

The application code is here:using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Reflection;

namespace qbTest_2{ public partial class form_1 : Form { public form_1() { InitializeComponent();

l_version.Text = Assembly.GetExecutingAssembly().GetName().Version.ToString();

if (!automaticUpdater.ClosingForInstall) { //// } } }}

Problem solved. Files "wyUpdate.exe" and "client" must be places to the application deploy directory. This information is not obvious in the guide.The error might be traced with automaticUpdater_CheckingFailed event.
