InnoSetup Script Joiner is a niche automation utility created by developer Bulat Ziganshin (hosted on platforms like the Krinkels.org community). It allows developers to quickly combine multiple Inno Setup (.iss) files into a single master installer script without writing manual Pascal code. Core Purpose & Value
When creating advanced Windows installers using Inno Setup, combining different functional scripts manually is incredibly tedious. If two different scripts use the same Pascal event handlers (like InitializeSetup), pasting them together manually breaks the compiler because duplicate function names are illegal.
The Script Joiner solves this by intelligently parsing and blending the structures automatically. Key Features
Code-Free Merging: Combines separate code blocks, components, and file structures automatically.
Intelligent Event Function Blending: It seamlessly merges up to 16 different native Inno Setup Pascal event procedures (such as InitializeSetup, CurPageChanged, NextButtonClick, BackButtonClick, and InitializeUninstall).
Logic Rules Resolution: When combining functions that return values, the utility applies custom AND/OR logic gates to ensure both scripts’ preconditions are checked properly.
Section Handling: Correctly processes complex multi-section .iss scripts as well as scripts containing pure code.
OS Integration: Includes a 64-bit Windows Explorer context menu integration for quick right-click merging. Alternative Native Approaches
If you do not want to use a third-party utility, Inno Setup natively provides a few alternative ways to manage and merge multiple installation workloads:
