No, there is no manual available. I have checked the official website, but nothing could be found. If you are an active customer, then you can log-in on the Member's area usint the following link: http://www.axelentsoftware.com/login.php?sel=5
It's possible that's the place to download the manuals from. If no file is listed in that area, then contact the developer and ask for a manual:
