If you define one of the functions listed below, Thinstall will call your function at the appropriate time.
Each .vbs script file can have one or more of these functions defined, each .vbs file will receive its own callbacks regardless of which other .vbs files are in your project.
Function OnRequirementsCheck
This function is called before the Installer is invoked. If no installer is enabled, this is called before OnProgramLoading is called. This function should be used to check for minimum system requirements before the installer is launched.
