If you have an internet connection on your computer then it is strongly recommended that you check for program updates on the web at the earliest opportunity.
From time to time we create updated versions of Solar Maps to fix problems and make minor enhancements to the program, and you can avoid unnecessary problems and get the benefit of any improvements by downloading and installing the latest patch update file.
You can check for such updates very easily by using the Solar Maps Help menu item described on Find Program Updates on Web, or otherwise simply by visiting our website (http://www.esotech.com.au/) and looking for links to patch updates.
