Update:

I found, that the problem is, that the original template is referenced in the resulting document. When I remove this information via File - Check Document in Word. I can load the merged document without error.

Now my problem is: How can I remove the reference for the original template via automation?

TIA

>I have a problem with a merged document. I create the document by MailMerge using a master template and a data source. The new document is created and saved. On some computers with different Word versions (2003 and 2013) Word wants a Data Source when I try to open the already merged document. I do not see any fields in the document. Opening the same document on another machine with Word 2013 no error comes up.
