This does not work with Visio 2013 Professional.

Feb 5, 2014 at 9:32 PM
Although the front page says that this is compatible with Visio 2013, it does not work. I have a licensed version of Visio 2013 Professional (32-bit) installed, and when trying to install the plugin, I receive the error:

"Setup cannot continue because SharePoint Network Topology Diagram Add-In (X86) requires that Visio 2010 Professional or greater be installed. Please install Visio and run setup again."

After clicking Ok, I receive the message:

"The installer was interrupted before SharePoint Network Topology Diagram Add-in (X86) could be installed. You need to restart the installer to try again. Click "Close" to exit."

Seeing as it appears that the plug-in hasn't been updated since February of last year, it is likely that no fix is forthcoming. Visio 2013 users, don't waste your time trying to install this.
