I have posted a new release (28.5-Sep-2018) in full installer and executable-only versions. Minor changes to help file.
The changes (taken from the update log) are:
Magnifier: Added buttons to Magnifier dialog box to allow viewing input image, output image, or both side by side.
Plug-ins Setup: fixed problem with plug-ins not being recognized until PWP was closed and re-opened.
