Outlook Previewer- How to activate with INFIX?

I use Outlook 2016 and want to preview pdf’s on my preview pane. How do get this to work with INFIX?
I get “This file cannot be previewed because there is no previewer installed for it” error.

Infix does not support preview generation in Outlook 2016. Adobe Reader which is free most likely does. I suggest you install Adobe Reader for this functionality.

Yes, the adobe reader worked. It is sad that I pay $99 for INFIX and have to use a free program to see my Outlook pdf previews.
