Inno Setup is a tool, designed for creating professional installation programs, which can run on all Windows platforms between Windows 2000 and Windows 11 (this includes business versions of this OS, with 32 and 64-bit versions also fully supported).

Although this open-source program can be used by anyone for free, Inno Setup is really stable and offers more features than most of its similar paid alternatives. 

This made it incredibly popular with worldwide audience who demanded access to perfect tools, wide OS support and advanced features such as complete uninstall tools, disk spanning, single EXE installers, support for multiple binaries inside a single package, INI/Registry management, integrated scripting engine (based on Pascal), passworded and encrypted packages, support for multiple compression algorithms, multilingual install interfaces and much more.

The first version of Inno Setup was created by developer Jordan Russell in IDE software package Embarcadero Delphi in distant 1997.

From that moment, this free software received countless updates and streamlining of a visual interface that can today easily be used by both users who have very little technical knowledge about software development and seasoned professionals.

The installers created with Inno can be of the conventional “wizard” type, can create shortcuts, launch or delete files, and can be password-protected or encrypted. The interface is not very intuitive, but various front-ends have been developed to make working with this product easier.

InnoSetup is a 100% free application that can be even used commercially, although its original developer is open to receive donations that are funding active development of this popular developer tool.

What's new in this version:

Changes related to custom styles:
- Previously, when displaying any RTF text with a custom style active (including the built-in custom dark style), all foreground colors were replaced by the style's foreground color. This has been improved to only replace default foreground colors, preserving any custom colors.
- Added new [Setup] section directive WizardImageOpacity to specify the opacity of wizard images. This is useful if you want to use identical regular and DynamicDark wizard images. For example, you can set it to 150 to achieve partial transparency. Defaults to fully opaque (non-transparent).
- The compiler now stores identical regular and DynamicDark wizard images only once.
- Documentation fix: The prototype of Pascal Scripting support function CreateCustomForm was changed in the previous version, but its documentation was not updated accordingly. This has now been corrected.

Security improvement:
- Added new [Files] section flag notimestamp, preventing the file from being stored with a timestamp. Use this flag to help make builds reproducible, even if you are unable to preserve timestamps on source files.

- Other minor improvements
