We have a PowerBuilder-application that opens document in Word.
With Office 2007 the following works for example:

Activedocument.ActiveWindow.ActivePane.View.Zoom.P ercentage = WORD_ZOOM_PERCENTAGE

.ActiveDocument.unProtect()

I am now testing Office 2016 and receive errors. I have looked at the Object Model and I don't see that anything has changed.

Any ideas?
