Word could not fire the event

Question

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

Word could not fire the event

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

I use the code below to test the issue:

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();
        }
    }
}

Here are my References:

The Code above throws a:

Exception thrown: 'System.Runtime.InteropServices.COMException' in WordTesting.exe

And the Console.Writeline is:

Exception: Word could not fire the event

Full exception:

System.Runtime.InteropServices.COMException: 'Word could not fire the event.'

UPDATE

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

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

Answer 1

Okay this is a strange solution. But I found it in here last post on this page and here

So basically it's a region thing. I had my region to ENG[DAN], because Denmark. But when I changed everything to ENG[US] it worked again.

I have some other parts of my implementation that still doesn't work, but for now this is good enough.
