Adding an MSI DLL Custom Action to Your Project
                                        InstallShield 2020 Express Edition
                                        
                                        The items in the Custom Actions view are organized by chronological order, according to when they are launched during installation or uninstallation. When you add a custom action to your project, you specify when the custom action should be launched by adding the action to the appropriate installation or uninstallation item.
                                        To add an MSI DLL custom action to your project:
