Version 3.5.3 seems to get the job done!
There is a lot I have yet to learn about creating EPUB files but version 3.5.3 appears to do the job when it comes to converting PDF files to the EPUB format. The program is not an editor but I should be able to create a different PDF file with changes I need to make and then covert to EPUB using this program. This program makes the job easy.
