The Geminon Software - Church Edition is an unsupported application at this time. This means I don't have the possibility to download or access any help files in order to check the envelope number. You'll have to rely on the built-in help to see exactly how Gemini Software needs to be configured. Either access Help > Help Contents or look in the installation directory for PDF, CHM, HLP and TXT files.
Developers usually place these files in the root directory of the installation. Currently, this is the only way to check for help documentation.
