Creating a Windows Installer package with WiX Toolset

Installer UI - welcome dialog

I have been working with Windows-based installation development for some time, and for some software projects that required simple deployment, I preferred to use a basic .msi installer package. And to do that, my first go-to tool is WiX Toolset.

Windows Installer XML (WiX) Toolset is a Microsoft open source project used to create the Office 2007 installer. WiX includes some advanced capabilities, but it has a steep learning curve even though the scripting language is using XML format. It took me some time to learn both technologies (WiX and Windows Installer itself), but it’s worth spending the time.

There are some advantages working with WiX toolset for creating Windows app installer and here are some of them that I can summarize based on my personal experience:

  • Source code in XML format, better clarity, easy to modify and debug.
  • Fresh clean .msi installer, no extra stuffs embedded, smaller file size.
  • Everything can be done using command-line, easy to integrate into CI build system.
  • Easy to source-control and edit using any code editor.
  • Good community support and a lot of examples. (You get one here too!)

In this post, I would like to share one example of my WiX project. Hopefully it would help for those who are looking to get started with WiX toolset, or for those may need to see more real-world examples of WiX-based projects.

  • app - Contains my application files to be installed
  • images - Contains graphic resource for customizing the installer UI.

WiX project files:

  • Product.wxs - Main file
  • Product.Var.wxi - Variables file. Included automatically into the main file during compile time.
  • Product.Loc-en.wxl - Localization file for custom strings used in the main file
  • MakeInstaller.bat - The batch script to compile WiX project files

        <?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>

    <?endif ?>

Note: BUILD_VERSION, BUILD_GUID and BUILD_PROJECTDIR are preprocessor variables that will be used in MakeInstaller.bat file to compile the WiX files.

Main WiX file

Below is the source code for my main WiX file to create a .msi installer. In this file, I have combined the code for my installer UI which includes few custom dialogs:

  • Custom license agreement dialog
  • Custom upgrade dialog
  • Custom install dir dialog (for Desktop shortcut option checkbox)
Image: With Create Desktop shortcut option
With Create Desktop shortcut option

Following are the extra features other the defaults that have been implemented into the source code:

  • Detect for minimum .NET Framework and OS version.
  • Detect if newer version is installed, and abort the installation.
  • Detect if older version is installed, show Upgrade Welcome Dialog, and skip License Agreement Dialog.
  • Prompt user to close if the application executable file is running during upgrade.
  • Create registry to memorize the installation directory path.
  • Create Start Menu and Desktop shortcut. Desktop shortcut is optional, user can choose to not create it.

Batch script for compiling the WiX project

These are the WiX toolset that I used in the script below:-

  • heat.exe - To automatically harvest my application files and generate a collection of <Component> elements and <ComponentGroup> that will be used in Product.wxs file under <Feature> element. Output from this tool is Product.Files.wxs file.
  • candle.exe - To generate *.wixobj file with some preprocessor variables.
  • light.exe - To compile *.wixobj and localization file using WiX extensions and generate *.msi file.


@echo off

set projectDir=.

Here’s the final project files structure after I run MakeInstaller.bat script:

WiX references

This project is done based on WiX v3.11 (GitHub) at the time I’m writing this post. If you need to customize your installer UI or to support multiple localizations, you can refer to this repository on GitHub for the code references.
