Inno Setup is a powerful and flexible tool for creating professional software installers for Windows applications. Inno Setup has been a trusted choice for developers since its initial release in 1997. The tool is highly praised for its simplicity and effectiveness, enabling developers to build comprehensive installation packages with minimal effort.

One of Inno Setup's standout features is its support for all versions of Windows, including the latest editions. It offers extensive customization options, allowing developers to tailor the installation process to meet their specific needs. The scripting engine is robust, providing the ability to handle complex installation tasks and conditional operations.

Inno Setup also supports multilingual installations, ensuring that software can reach a global audience. The tool includes features such as integrated file compression, password protection, and support for digital signatures, enhancing the security and integrity of the installation packages.

Inno Setup is open-source, offering developers the flexibility to modify and extend the software to suit their unique requirements. The active community and comprehensive documentation make it easy to get started and find solutions to common challenges. With its blend of ease-of-use, power, and versatility, Inno Setup remains a top choice for developers looking to create reliable and user-friendly installers.

Key Features:

• Multiple Installation Types: Create full or minimal installations based on user choices.
• Custom Scripts: Use Pascal scripting for tailored installation processes.
• Multilingual Support: Easily create installers in different languages.
• Disk Spanning: Split installers across multiple disks for large applications.
• File Compression: Reduce installer size with built-in compression options.
• Automatic Uninstaller: Generates an uninstaller for easy software removal.
• Digital Signing: Supports signing installers for enhanced security.
• Good Documentation: Well-documented with strong community support for help and resources.

• /LOG: Now logs INI entries. Also improved logging of icon entries.
• Added new [Setup] section directive: Output, which defaults to yes. If set to no the Setup Compiler will only check the script for errors and skip creating setup files.
• Console-mode compiler (ISCC) changes:

1. Added new command line parameters /DO and /EO. These can be used to disable or enable output, overriding the Output directive.
2. Added new command line parameter /Qp. Can be used to enable quiet compile while still displaying progress. Contributed by KngStr via GitHub.
3. ISCC now automatically specifies any Sign Tools configured using the IDE, eliminating the need to specify these using the /S command line parameter. Also contributed by KngStr via GitHub.

• Pascal Scripting changes:

1. Added new function CurrentSourceFileName, which returns the source file name of the [Files] entry that is currently being processed. The returned name may include constants. Note: Do not attempt to call this function from outside a Check, BeforeInstall or AfterInstall event function belonging to a [Files] entry with the external flag.
2. The already-existing StrToFloat and FloatToStr functions are now documented.
3. Strings and numbers are now highlighted. Based on contribution by maldoinc via GitHub.
