Stable Release

Inno Setup 6 introduced a number of significant enhancements including:

  • 6.0: Improved support for administrative vs. non administrative install mode.
  • 6.0: Overridable install mode by the end user at runtime (example if PrivilegesRequired is set to admin.)
  • 6.0: Improved support for side-by-side installations without the odd side effects you would get in previous versions.
  • 6.0: Optional support for a resizable wizard window.
  • 6.0: New optional modern wizard style (example.)
  • 6.0: Other changes for a more modern look to Setup, Uninstall, and the Setup Compiler.
  • 6.0: New light and dark themes, new toolbar icons and new per-monitor DPI awareness mode for the Compiler IDE (light theme example, dark theme example.)
  • 6.0: Event attributes, making it possible to have multiple implementations of the same event function in your script.
  • 6.0: Support for 64-bit mode on Windows 10 on ARM.
  • 6.0: Task dialog support for the [Code] section.
  • 6.1: Many improvements to the Compiler IDE including support for editing and debugging of #include files and viewing the preprocessor output directly.
  • 6.1: Support for downloading files without using a third-party tool and easily showing the download progress to the user.
  • 6.1: Support for per-user fonts if Setup is running on Windows 10 Version 1803 and later.
  • 6.2: Graphics modernized, including the automatic use of higher quality images (which were not available before) on higher DPI settings.
  • 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.

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.

Change in default behavior: Starting with Inno Setup 6 there's only one version available: Unicode Inno Setup. Unicode Inno Setup has been available for since 2009 but in case you have not yet updated to it: please see the Unicode Inno Setup topic in the help file for more information. Basically, unless you're using [Code] to make DLL calls with string parameters you shouldn't have to make any changes to your script.

Encryption Module

For legal reasons, encryption code is not built into Inno Setup. You must download a separate "encryption module" if you wish to utilize Inno Setup's encryption capabilities (that is, the Encryption [Setup] section directive). Note: The installer above can download and install it for you.
