InstallShield Overview
InstallShield is a long-established Windows application packaging tool from Flexera (formerly part of its developer line), used to build professional installers for Windows software. It lets developers and release engineers create reliable setup programs that handle the full range of installation tasks: copying files, writing registry entries, creating shortcuts, installing prerequisites and runtimes, registering components, and configuring services. InstallShield can produce standard Windows Installer (MSI) packages, traditional InstallScript-driven setups, and modern MSIX packages, and it supports advanced scenarios such as suite installers that chain multiple packages, multi-language setups, digital signing, and silent or unattended installation for enterprise deployment. It integrates with Visual Studio and continuous-integration systems so that building installers can be automated as part of a software release pipeline. It is a commercial product, offered with a free trial. This page links to the official InstallShield download.
