InstallShield

InstallShield is a commercial installer authoring tool used to create Windows installers for software applications. It provides a project-based environment that lets developers define how their software is installed, updated, and removed on Windows. InstallShield can produce MSI-based packages that rely on the Windows Installer service and executable installers. It also supports InstallScript and InstallScript MSI for custom installation logic.

Key features include a graphical dialog editor, file and registry operations, shortcuts, service installation, and condition-based flows. InstallScript offers a procedural language for complex setup tasks, while MSI-based installations use Windows Installer actions. The tool supports prerequisites, patches (MSP), upgrades, localization for multiple languages, digital signing, maintenance mode, and both web and traditional installers. It also provides silent/unattended install options and rollback support.

Automation and integration: InstallShield includes a command-line build tool and integrates with common build systems and version control. It enables testing, packaging, and updating via patch packaging, and supports deployment prerequisites.

Limitations and reception: InstallShield is a mature, feature-rich solution with a relatively high license cost and a learning curve. It competes with other installer technologies and package ecosystems, including MSI-based approaches and open-source options. It remains widely used by software vendors and enterprise developers for professional Windows software distribution.
