The Lighthouse Studio installer uses an installation software called Inno Setup (https://jrsoftware.org/isinfo.php).
Here is an example of how the installer can be run silently with specific options selected:
LighthouseStudio_9_9_0_Setup.exe /VERYSILENT /NORESTART /TASKS="uninstallpreviousversionsautomatically,excelplugin,desktopicon"
/SILENT, /VERYSILENT
Instructs Setup to be silent or very silent. When using /SILENT, the wizard and the background window are not displayed but the installation progress window is. When using /VERYSILENT, the installation progress window is not displayed. However, error messages during installation are displayed, and if the installer requires Administrative priveleges, the prompt will still be displayed. If a restart is necessary and the '/NORESTART' command isn't used (see below) and using /SILENT, it will display a Reboot now? message box. If using /VERYSILENT, it will reboot without asking.
/NORESTART
Prevents the installer from restarting the system following a successful installation, or after a Preparing to Install failure that requests a restart. Typically used along with /SILENT or /VERYSILENT.
/TASKS="comma-separated list of task names"
/TASKS specifies a comma-separated list of installer options that should be selected as part of the install (options normally selected by a user during install). Tasks for the Lighthouse Studio installer include:
uninstallpreviousversionsautomatically
This task will uninstall all previous versions of Lighthouse Studio.
excelplugin
This task will install the Excel plug-in for Randomized First Choice.
desktopicon
This task will place a shortcut to Lighthouse Studio on the desktop.
