MS Word 2013 ActiveDocument.MailMerge.OpenDataSource not available for reading on opening a document

A new PC has MS Office 2013 when the system still uses Office 2003 templates and vba code.

Error:

Don’t have actual text to hand, but something like:

“MailMerge.OpenDataSource is not available for reading”

Solution:

Programmatically change the view on open:

Private Sub Document_Open()
Me.ActiveWindow.View.Type = wdNormalView
End Sub

Found solution on web. Following was not the page, but similar
