Until now the only Windat file opener that works 100%

I have tried and even purched other Windat File openers, but this program proved to be the best on available. It opened 100% of the Windat files I have received so far, being able to extract both the e-mail message (intact) and the attached files (mostly PDF files).
I am running on OS X El Capitan 10.11.5
