Version 2.3 has enhancements to make it much more user friendly. There is no need to download Sky Commander software and
catalogs separately; they are installed automatically in the application directory, i.e.
C:\Program Files (x86)\Sky Engineering\XP4_Flash2v3
If you have version 2.0 to 2.2 installed, please uninstall and reinstall version 2.3 in order to avoid problems.
