Stable Release

Inno Setup 6 introduced a number of significant enhancements including:

• 6.3: Support for UTF-8 encoded files without a BOM.
• 6.3: Support for Arm64 systems improved, and related enhancements.
• 6.3: Many Compiler IDE improvements, including multiple selection support.
• 6.3: Support for logging the output of executed programs or batch files.
• 6.4: Many more Compiler IDE improvements, including match selection, parameter hints, improved autocompletion, section folding, change history and optional Visual Studio Code-style shortcuts.
• 6.4: Improved encryption and updated LZMA SDK.
• 6.5: Improved archive extraction.
• 6.5: Improved file downloads.
• 6.5: New signature-verification capability.
• 6.5: Full dark mode support for the Compiler IDE, and improved support for high-contrast themes and screen readers.
• 6.5: Support for encryption of the entire installation.
• 6.5: Introducing unique builds.
• 6.5: Introducing commercial licenses.

OS requirements change: Windows Vista and Windows Server 2008 are no longer supported. Windows 7 and Windows Server 2008 R2 are now the minimum supported operating systems. [Setup] section directive MinVersion still defaults to 6.1sp1, so by default Setup will still not run versions of Windows 7 and Windows Server 2008 R2 which have not been updated.

What's new in this version?

Introducing commercial licenses: Using Inno Setup commercially? Please purchase a license. Thank you! All commercial licenses are perpetual and require a single payment. They include two years of updates, major and minor. After this period, your current version will remain licensed and functional as-is.

To install Inno Setup interactively using winget use the following command: winget install --id JRSoftware.InnoSetup -e -s winget -i
