What is an IWZ file? An IWZ file is a project created by Flexera InstallShield Express 2.x, a tool that helps developers create installation packages for Windows applications. It contains key components of an installation project, such as configuration settings, file paths, InstallScript code, and user interface ( UI ) elements like dialog text and images.

More Information InstallShield Express was a simplified version of the full InstallShield tool. Developers used IWZ files in older versions of InstallShield Express from the early 2000s to organize and save the setup process for their software so they could compile it into an installer. Modern versions of InstallShield no longer use IWZ files, making them obscure.
