If you can’t download the VSTO

The Add-in works on Microsoft VSTO 2010.  It uses Microsoft VSTO to complete the download of the app.  Occasionally, this software (Visual Studio Runtime for Office) can have a bug in it. 

You can download this runtime package from Microsoft to detect if VSTO is already installed on your computer and/or to directly install it if needed:  http://go.microsoft.com/fwlink/?LinkId=140384

 After you’ve installed (or reinstalled) VSTO, then start the Add-In setup again.
