We already looked at the Trust Center in a previous tutorial. But who knew that there so many settingsavailable within the Trust Center? In this tutorial, we will explore these settings withinPowerPoint 2016.

Follow these steps to get started:

By default when a location is trusted, its sub-folders will not be trusted. To change that, we will add a REGDWORD (binary) key. The name of the key is: AllowSubfolders The value of the key is: 1 Path The value of the key is the full path to your project (don't forget the ending slash). To add a new location to the list we will add a REGSZ. Require Application Add-ins to be signed by Trusted Publisher Check this box to have the Trust Center check that the add-in uses a publisher's trusted signature. If the publisher's signature hasn’t been trusted, the Office program doesn’t load the add-in, and the Trust Bar displays a notification that the add-in has been disabled.

1. Bring up the Trust Center dialog box as explained in ourTrust Center in PowerPoint 2016 for Windowstutorial as shown in Figure 1, below.
