What's new in this version?

Remember to check the Inno Setup FAQ for solutions to common problems. Also see the Third-Party Files page for some useful tools, and translations of Setup into other languages.

QuickStart Pack

The Inno Setup QuickStart Pack includes Inno Setup itself and additionally includes an option to install the Inno Script Studio script editor. This script editor is not official and is not required for general usage, but makes Inno Setup easier to use. See the Third-Party Files page for more information.

The Inno Setup QuickStart Pack also includes an option to download and install official encryption support.

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 above QuickStart Pack can download and install it for you.

Beta Release

A beta release of Inno Setup 6 is available and introduces a large number of changes. You are welcome to discuss its features on the forum.

Some features included in Inno Setup 6 are:

• Improved support for administrative vs. non administrative install mode.
• Overridable install mode by the end user at runtime (example if PrivilegesRequired is set to admin.)
• Improved support for side-by-side installations without the odd side effects you would get in previous versions.
• Optional support for a resizable wizard window.
• New optional modern wizard style (example.)
• Other changes for a more modern look to Setup, Uninstall, and the Compiler IDE.
• 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.)
• Event attributes, making it possible to have multiple implementations of the same event function in your script.
• Support for 64-bit mode on Windows 10 on ARM.
• Task dialog support for the [Code] section.
• Many more improvements and new features.

For the complete list of what's new/changed, see: What's new in this beta version?

OS requirements change: Windows 2000, XP, and Server 2003 are no longer supported. Windows Vista is the minimum supported operating system.

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 9 years 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.

Beta releases are not recommended for production use.
