## What it is
Inno Setup is an open-source installation builder for Windows applications, first released in 1997. It compiles scripts into a single setup EXE with a standard Windows wizard interface, supporting 32-bit, 64-bit, and Arm64 installs.

## Use cases
- create a windows installer for my app
- build a single exe setup file for software distribution
- make an installer with uninstall support and add/remove programs entry
- create a silent install package for deployment
- package an application with registry entries and shortcuts
- build an installer supporting 64-bit and arm64 windows

## When to choose
- you need to deploy a Windows desktop application with a professional setup wizard
- you want a free, battle-tested installer with script-based configuration
- you need support for x64, Arm64, and administrative or non-administrative installs

## When to avoid
- you are targeting Linux or macOS installers
- you need MSI packages specifically for enterprise group policy deployment
- you want a GUI-only drag-and-drop packaging tool without scripting

## Facets
- artifact type: application
- maturity: stable
- function: developer-tools, deployment, cli
- domain: developer-tools, windows
- platform: windows, cli
- tags: installer-builder, setup-wizard, pascal, software-deployment, automation
