Introduction
Imagine you're a software developer, and you've just completed an awesome new program that you're eager to share with the world. But wait, there's one crucial step left - how are you going to get your software installed on your users' computers? This is where Inno Setup comes in to save the day!
Inno Setup is a free, script-driven installation system for Windows that makes distributing your software a breeze. Created in 1997 by Jordan Russell, this powerful tool has become a favorite among developers who want to create professional-looking, customizable installers without all the hassle.
In this article, we'll dive into the world of Inno Setup, exploring its history, key features, and the many ways it can simplify your software deployment process. So, let's get started and unlock the secrets to seamless Windows installations!
The Birth of Inno Setup
Back in the 90s, when software distribution was still a relatively new frontier, Jordan Russell was searching for a better way to create Windows installers. He had tried using InstallShield Express, but found it to be too limited for his needs.
Determined to find a more flexible solution, Russell set out to create his own installation system from scratch. Thus, Inno Setup was born - a free, open-source tool that would soon become a beloved resource for developers around the world.
What makes Inno Setup so special? Well, for starters, it's completely script-driven, which means you can customize every aspect of the installation process using a Pascal-based scripting language. This allows you to create highly tailored installers that perfectly match the branding and functionality of your software.
But Inno Setup isn't just about customization - it's also incredibly efficient. With its built-in support for multiple compression algorithms, including DEFLATE, bzip2, and LZMA, your installers can be compact and lightning-fast, ensuring a smooth experience for your users.
Building and Compiling Inno Setup
If you're ready to dive into the world of Inno Setup, the first step is to get the source code. You can find the latest version on the project's GitHub page, where you'll also find instructions on how to build and compile the software.
The process is surprisingly straightforward. Simply download the source files, navigate to the appropriate directory, and run one of the provided batch files (such as `build.bat` or `compile.bat`) to get the job done. For the Community Edition, you'll need to open the `Projects\Projects.groupproj` file instead.
But wait, there's more! To fully customize your Inno Setup projects, you'll need to install some specific component units found in the `Components` directory. These include BidiCtrls, BitmapImage, FolderTreeView, and others, which will allow you to modify the setup project's forms and user interface.
And if you're looking to streamline your development workflow even further, Inno Setup also includes a handy GitHub workflow for unattended builds. This requires setting up an encrypted zip file containing the necessary Delphi files and uploading it to a public location, but the end result is a seamless, automated build process that can save you tons of time.

Now that you know a bit about the history and setup process, let's dive into the juicy details of what makes Inno Setup such a powerful tool for Windows installations. Here are some of its key features:
