Acrobat DC - CreateObject - Visibility

[Guest]

In previous Acrobat Versions I was creating a instance of the Acrobat Writer by the following code:

Dim objAcrobat = CreateObject("AcroExch.PDDoc")

after the update to Acrobat DC the above code creates the Acrobat instance and shows the Acrobat visible. In the previous version it was invisible.

How can I create a Acrobat instance invisible.

Thank you
