title: Word could not fire the event
body: <p>I have been using the Microsoft Office Interop Word for quite some time without any issues, but now all of a sudden it has stopped working.
  It now gives me the exception message</p>
  
  <blockquote>
    <p>Word could not fire the event</p>
  </blockquote>
  
  <p>I'm running the latest update of Windows 10 Pro - 1809, I have office 2016 installed also with the latest updates.
  And I'm running Visual studio 2017</p>
  
  <p>I use the code below to test the issue:</p>
  
  <pre><code>using System;
  using Word = Microsoft.Office.Interop.Word;
  
  namespace WordTesting
  {
      class Program
      {
          static void Main(string[] args)
          {
              Word.Application application = new Word.Application();
              application.Visible = false;
              Word.Document document = null;
              try
              {
                  document = application.Documents.Open(@"C:\Users\caspe\Desktop\TEST.docx", Visible: false);
              }
              catch (Exception e)
              {
                  application.Quit();
                  Console.WriteLine("Exception: {0}", e.Message);
              }
              Console.ReadKey();
          }
      }
  }
  </code></pre>
  
  <p>Here are my References:

  <p>The Code above throws a:</p>
  
  <pre><code>Exception thrown: 'System.Runtime.InteropServices.COMException' in WordTesting.exe
  </code></pre>
  
  <p>And the Console.Writeline is:</p>
  
  <pre><code>Exception: Word could not fire the event
  </code></pre>
  
  <p>Full exception: </p>
  
  <pre><code>System.Runtime.InteropServices.COMException: 'Word could not fire the event.'
  </code></pre>

    <p>UPDATE</p>
    
    <p>I have just tested my build on another windows 10 machine with build 180 and there it works like a charm</p>

  <p>I hope someone can find a solution to the issue, because I haven't been able to find one.</p>
