The installer is written using Innosetup. You will need to download and install this software before continuing. As of this writing the installer was written using version 1.2.2
The install file expects a certain setup of how the folders will look. Here is how to setup that folder structure.
You should be now configured to build the OpenSong installer. Your directory structure should look like this.
OpenSong
|_ InnoSetup
|_ OpenSong Defaults
| |_ Backgrounds
| |_ Sets
| |_ Settings
| |_ Songs
|_ OpenSong Languages
|_ OpenSong Scripture
|_ OpenSong Settings
To customize your installation just add the backgrounds, sets, or songs into your OpenSong Defaults folder. The installer will automatically include these. In the Settings folder you can edit the configuration files to make them whatever default you would like.
It will run through the compile and tell you any errors if everything is ok then you will have the installer in the “OpenSong”→“InnoSetup”→“output” folder.
