"JFX faxes are TIFF docs (no special software needed)"
When I had Windows XP 32-bit this software was alright to use, but I would have preferred a more standard fax viewer.
This software does not work on Windows 7 64-bit.
There is no need for special software to view JConnect faxes. Just rename the file extension from *.jfx to *.tif, and use your standard TIFF viewer to display the fax.
Alternatively, upload/sync the JFX file to your Google Drive account, you can view the fax online and print it as a PDF.
