Hi pbastiaans,

We did the following to fix the issue:

Create an appstack using a 2.13 template.

Provision to an app packaging machine that has Office 2016 installed.

Install Visio 2016.

DO NOT OPEN Visio after install completed.

Finish provisioning.

Assign to user, and log into QA/Prod machine.

Open Visio...profit!.

Evironment details:

AppVols 2.16.

Windows 10 1709.

Office 2016 (x86 - Patched to Feb 2019) installed in Gold image.
