C# CreateProcess for an IE URL fails on 64bit

In C# VS2010.NET I have: 

try
{
   string ieFullPath = System.IO.Path.Combine(Environment.GetFolderPath(
      Environment.SpecialFolder.ProgramFiles), "Internet Explorer\iexplore.exe");
   if (File.Exists(ieFullPath))
   {  
      this.CreateProcess(""" + ieFullPath + "" "" + updatePage + """);
      MessageBox.Show("A Run");
   }
}
catch
{
   MessageBox.Show("A Fail");
}
try
{
   string ieFullPathX86 = System.IO.Path.Combine(Environment.GetFolderPath(
      Environment.SpecialFolder.ProgramFilesX86), "Internet Explorer\iexplore.exe");
   if (File.Exists(ieFullPath))
   {  
      this.CreateProcess(""" + ieFullPathX86 + "" "" + updatePage + """);
      MessageBox.Show("B Run");
   }
}
catch
{
   MessageBox.Show("B Fail"); 
}


I added in alerts and can see that both of the CreateProcess calls do run and neither of them causes an exception, yet on 64-bit Windows neither actually open a web page. Since neither throw an exception I also cannot 'detect' in the code that the problem occurred in order to show a suitable error message to the user, I can only see it when testing.

How can I enable the process of opening a web page so that it will work under 32-bit and 64-bit machines please? As the latter does not work for me at the moment.

Hi Rabbit,

You can use the Navigate method of the IE object model to open an url in a separate IE window or tab.
