If you installed the 32-bit edition of preview-1, please uninstall it yourself before installing preview-2, because its AppId has changed.
Comparing preview-2 to preview-1:
Changes related to 32-bit vs 64-bit:
- The 32-bit edition of Inno Setup's own installer now supports a non-administrative install again.
- Added new System Path Redirection help topic.
- Pascal Scripting:
- Fixed an issue with the built-in TFindRec record type in 64-bit installers.
- Added the following note:
- In both 32-bit and 64-bit installers, Pascal Script records are always "packed". When calling a Windows API or external DLL function that expects aligned records, you may need to add manual padding fields. Even if this was not needed in a 32-bit installer, it may be needed in a 64-bit installer because alignment rules and field sizes differ.
- We tested support of Windows Server Core with WOW64 removed:
In our tests on 'Windows Server 2016 Datacenter Server Core' and 'Windows Server 2025 Datacenter: Azure Edition Core', with all WOW64 features disabled and removed using DISM, 64-bit installers still function correctly, even when run in 32-bit install mode. - Improved 'regtypelib' handling and documentation.
Other changes:
- [Setup] section directive ArchiveExtraction can now also be set to auto, the new default.
- Pascal Scripting: Added new optional OnLog parameter to the [Run] section.
- Updated the 7-Zip and LZMA SDK source code used by Inno Setup to the latest versions.
- As a proactive security measure, the compiler no longer allows .isl message files specified in the [Languages] section to contain compiler directives such as #include.
- Other minor improvements.
Please test your scripts and installers with this preview, even if you do not intend to use 64-bit installers, and report success or failure by sending a quick email to innosetup@googlegroups.com (preferred) or mlaan AT innosetup.nl. Thank you in advance. Especially please test and report this functionality:
- Using 64-bit install mode in a 32-bit installer.
This is not new functionality but we did many changes related to system path redirection. - Using 32-bit install mode in a 64-bit installer.
- Using Pascal Scripting in a 64-bit installer.
Please do first ensure your script is actually compatible with 64-bit execution. Whatsnew (linked below) has some tips about this.
Please do not use this preview to build installers you will use in production.
Here are the general notes:
We are proud to announce the first preview of Inno Setup 7, which includes a 64-bit edition, as well as a 32-bit edition.
Both editions of Inno Setup 7 can build either 32-bit or 64-bit installers, and they can be installed side by side, and they can coexist alongside Inno Setup 6.
Additionally, support for extended-length paths was added, removing MAX_PATH limitations.
Great care has been taken to ensure maximum backward compatibility with Inno Setup 6, including backward compatibility for the extended-length path support, and compatibility between 32-bit and 64-bit installers.
