InstallOptionsEx Readme

Introduction

InstallOptionsEx is a NSIS plugin which allows you to create custom pages for NSIS installers, to prompt the user for extra information. This is a expanded version of original InstallOptions, with additional controls, flags and options.

InstallOptionsEx will create a dialog which will be displayed inside the NSIS window. The controls on the dialog can be defined in an INI file.

NSIS 2 has a page system which allows you to add custom pages to your installer without messing with Prev/Next functions. With the this plugin system, you also don't have to worry anymore about extracting and deleting the DLL file. When you store the INI files in the plugins directory, NSIS will also delete them automatically.

This version of InstallOptionsEx has been designed for NSIS 2. It supports customized user interfaces and custom font and DPI settings.

This documentation uses the expand/collapse effect, making information to be in levels. Click on one item name which have an icon to see its respective description.

INI File Structure

This is where everything about the INI file is explained. Changes to the INI file structure since InstallOptions are represented by these colors:

	Old and supported (InstallOptionsEx/InstallOptions)
	New and supported (InstallOptionsEx only)
	Old but not supported (mainly InstallOptions only)

In this documentation section, items are organized as follows:

  Section
  - Value name (Required) (Input/Output)
    - Flag OR Control Type (With Exceptions)
      - Flag ("Control Type Exceptions")

Your INI file should have this structure based on the information above:

  [Section]
  Value name=Value (or Flag(s))

Changed State and Notify INI value names from Settings INI section:

Fixed: State had the value of 0 and Notify didn't even appear when OPEN_FILEREQUEST, SAVE_FILEREQUEST or DIRREQUEST were used on a Button control.

As the appearance of these INI value names are imminent: If State = 0, the page returned a notification. If Notify = ONNEXT, ONBACK or ONCANCEL, the user clicked on next, back or cancel buttons, respectively.
