You are attempting to open a file type

You are attempting to open a file type (Visio 2000-2002 Binary Drawings, Templates and Stencils) that has been blocked by your File Block settings in the Trust Center.
Click the File tab.
Click Options.
Click Trust Center, and then click Trust Center Settings.
In the Trust Center, click File Block Settings.
