wwlib.dll crashes Word randomly while editing using Interop.Word RRS feed

  • Question

  • We’re using Microsoft.Office.Interop.Word  to update values in a Word template from C# from a desktop application. 

    The implementation loops over a dictionary with bookmarks as keys and texts as values. For each entry in the dictionary the following method is used to set the text.

            public void SetFormFieldText(string name, string text)
                var range = Microsoft.Office.Interop.Word.Document.GoTo(Name: name);
                range.Text = text;

    This works most of the time, but seemingly random, maybe one time in three, word crashes in module wwlib.dll. When that happens it may work using the same template with the same values.

    This gives the following entry in the event log

    Faulting application name: WINWORD.EXE, version: 16.0.11328.20468, time stamp: 0x5dbb4fb9
