Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.
Changelog:
For better appearance on Windows 7 and Vista when ClearType is enabled,
Tahoma is the new default font used by Setup and Uninstall. A new [Setup]
section directive DefaultDialogFontName has also been added to make
it easy to override the default dialog font for all languages that do not
have a custom DialogFontName setting. If you would like to revert
to the dialog font used in previous versions of Inno Setup (Microsoft Sans
Serif if available, else MS Sans Serif), set DefaultDialogFontName
to an empty string (DefaultDialogFontName=).
Added new [Setup] section directive: DisableWelcomePage to hide
the Welcome wizard page. Doing so is recommended by the Aero wizard
guidelines. Additionally, the ShouldSkipPage event function is now
also called for wpWelcome.
When Setup is not running silently, the Ready To Install wizard
page now ignores attempts to skip it when no other wizard page before it has
been shown yet.
Added LZMA2 compression support:
Updated the LZMA SDK
compression code to version 9.10 which adds support for LZMA2
compression. LZMA2 is a modified version of LZMA that offers a better
compression ratio for uncompressible data (random data expands about
0.005%, compared to 1.35% with original LZMA), and optionally can
compress multiple parts of large files in parallel, greatly increasing
compression speed but with a possible reduction in compression ratio.
LZMA2 compression may be activated by setting the Compression
[Setup] section directive to lzma2, and lzma2 is now
also the default value.
Added various new [Setup] section directives with names that start with
LZMA to fine-tune LZMA and LZMA2 compression parameters, including
LZMADictionarySize which allows the LZMA dictionary size to be
increased up to 256 MB from the previous maximum of 64 MB. Review the memory
requirements listed in the Compression topic before using.
Tweaked the JMP/CALL instruction optimization algorithm for slightly
better compression of executable files. (On Inno Setup's own installer, this
saved about 2 KB.)
Improved compression of x64 executable files: just like for x86
executable files, JMP/CALL instruction optimization is now performed for x64
executable files. On average, this will reduce the compressed size of x64
executable files by 2-3%.
[Setup] section directive DiskSliceSize can now be set to
max, and max is now also the default value.
Windows 7 change: The Compiler IDE is now pinnable. Also, files that are
opened via the Welcome dialog, MRU list, and drag & drop now get added to
the Jump List.
Windows 7 and Vista changes:
Before deleting a pinned shortcut, Uninstall now automatically
removes it from the current user's Start menu pinned list and on Windows
7 also from the taskbar.
Changed the icon that is shown on Select Start Menu Folder
wizard page. Previously, it used the same icon as the preceding
Select Destination Location page, but that was never really the
intention.
When Setup and Uninstall respawn for elevation, any SUBST'ed drives
in the EXE filename are now expanded before the respawn, since the
elevated user will not retain the original user's SUBST mappings. Fixes
error seen when starting Setup from a SUBST'ed drive.
Setup now uses the SHA-1 algorithm instead of MD5 for file checksums and
various internally-used hashes.
Pascal Scripting: Added support functions GetSHA1OfString,
GetSHA1OfUnicodeString, and GetSHA1OfFile.
QuickStart Pack: Added ISPP functions GetSHA1OfString,
GetSHA1OfUnicodeString, and GetSHA1OfFile.
[Icons] section parameter AppUserModelID is now also used on
Windows Server 2008 R2.
Unicode Inno Setup: Added workaround for upstream Delphi bug that could
cause Setup (versions 5.3.6 to 5.3.8) to display a "Stream read error" error
message at startup on Windows 2000 systems that did not have Service Pack 4
installed.
Compiler IDE change: the Tools | Configure Sign Tools... dialog
now allows editing of existing Sign Tools.
The uninstall program's version is now 51.(10)52.0.0.
Minor tweaks.
