Painter 2017 .rif thumbnail not showing in file explorer.

I only see the icon for painter 2017 when looking at my files in Windows 10 file explorer.  I went through the steps Skip explained for this problem with version 2016 but that did not help.  The only thing that shows is the brush over the green simulated brushtroke.

Is there a way to see the thumbnails with this new version?

Thanks for any help with this.
