Inno Setup 7.0.0-preview-3

Changes related to 32-bit vs 64-bit, compared to preview 2:

• Uninstall: Fixed a 'PathRedir: Not initialized' error occurring when uninstalling without a [Code] section present.
• Pascal Scripting: Added types LONG, ULONG, LONG_PTR, ULONG_PTR, HANDLE, COLORREF, HINSTANCE, SIZE_T, SSIZE_T.
  These new types complement similar types which were already available.
  If your script already included a custom definition of one of the new types, you should simply remove this definition.

Other changes compared to preview 2:

• Compiler IDE: Find in Files, Replace All, and Select All Find Matches could enter an infinite loop, or miss a valid match at the end of the text, when using a regular expression that matches zero-length text (for example ^ or \b).
• [Setup] section directive AppVerName now defaults to AppName AppVersion (just a space separating the values) rather than AppName version AppVersion (localized). If you prefer to keep the word "version" (localized), use the NameAndVersion custom message: AppVerName={cm:NameAndVersion,My Program,1.5}
• [Setup] section directive TimeStampsInUTC now defaults to yes.
• Pascal Scripting: Fixed support functions InitializeBitmapButtonFromIcon (broken since its introduction) and InitializeBitmapImageFromIcon (broken since 6.5.0).
• ISPP: Fixed handling of relative filenames by support functions ReadIni, WriteIni, and Is64BitPEImage to be the same as other file-related support functions.
• Setup: Split the help text shown by the /HELP command line parameter across two message boxes for easier reading.
• [Files] section entries with the extractarchive flag could fail to extract any files from an archive if the first entry in the archive didn't match. For example, if the archive contained a file in a subdirectory as its first entry (for example, subdir\file1.txt followed by file2.txt) and recursesubdirs was not used, no files would be extracted at all, not even file2.txt.
• Many other minor improvements and fixes.

Inno Setup 7.0.0-preview-2

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.
