Program downloaded and installed flawlessly to Windows 7 Ultimate.
I chose a newly downloaded PDF file at random and did a test conversion to epub. I was not impressed by the result. Many pages were unintelligible gibberish. The free Calibre is far superior, and retains the original cover, something this program does not do. Also, Calibre provides a built-in reader.
My advice is don’t waste your time with it. I’m very thankful I did not pay for this.
