REQUIRED: You need to have Inno Setup installed:

- Inno Setup 5.6.1 (Ansi or Unicode) installed -

OPTIONAL: To edit Inno Setup scripts you need any text editor (e.g. Notepad) or you can use advanced IDEs. These are recommended:

- Visual & Installer (recommended tool - Visual Studio 2005 - 2017 extension with syntax highlighting, complete word functionality, ...) -

- RAD & Installer (Embarcadero RAD Studio 2009, 2010, XE - XE8, 10 Seattle - 10.2 Tokyo expert with syntax highlighting, complete word functionality, ...) -

Please notice:

To create FULL Unicode installers use ***Unicode*** version of all used plug-ins with Unicode build of Inno Setup.


1. Follow the automatic Setup Wizard.

2. During the setup process all necessary components will be installed, if they are not present on your machine.
For correct function of Graphical Installer these components will be installed:

- InnoCallback plug-in (v1.0.0.0)

- GraphicalInstaller plug-in v1.10.0.1

- Graphical Installer core files (.iss files, .exe files, documentation and other tools)

- Graphical Installer Wizard v1.10.01 (optional) - for Visual & Installer, RAD & Installer, Inno Script Studio and standalone application

- Examples

- Skins

3. At page 'Select Destination Location' choose path to your Inno Setup directory (if not found automatically).
Graphical Installer cannot be installed into other directory, because it is tightly linked with Inno Setup core files!

4. At page 'Select Graphical Installer version' choose which version to install: Ansi or Unicode.
Both versions can be installed on the same machine (into different directories).

5. The Setup process offers you to install Inno Setup IDEs. They are recommended, but not required for Graphical Installer.

6. When Setup finishes run your preferred IDE. There is 'Graphical Installer' option in the main menu. Use it to create new installers or to convert your existing scripts.

Creating an installer

You have several options:

1) To create scripts manually from the scratch.
2) To edit some of the Examples script (which can be found in Graphical Installer\Examples directory)
3) To use a supplied Graphical Installer Wizard plug-in (Wizard.exe in {Inno Setup}\Graphical Installer directory), which has a lot of functions and will generate new or convert existing scripts for you.
4) To use a Visual & Installer - Visual Studio extension for creating Inno Setup installers directly from Microsoft Visual Studio 2005 - 2017.
It also contains Graphical Installer Wizard so you have all tools in one package - download from
5) To use a RAD & Installer - Embarcadero RAD Studio expert for creating Inno Setup installers directly from RAD Studio 2009, 2010, XE - XE8, 10 Seattle - 10.2 Tokyo.

Few tips:
- Read the comments in the .iss files, there is a lot of information
- Browse the Graphical Installer\Examples directory, there are several useful examples
- Graphical settings are configured via .graphics.iss file. This file is unique for each project
- Functions and various macros are defined in GraphicalInstaller_functions.iss file. Do not edit this file if you are not an Inno Setup expert
- All projects using Graphical Installer must have defined symbol GRAPHICAL_INSTALLER_PROJECT in the .iss file
- If this symbol is not found the script is compiled normally (without skinning)
- See examples and tutorials for Inno Setup, they can teach you a lot!
- Background image size is exactly 690x496 pixels. Other files can be generated via BitmapCutter.exe tool
