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.
Key features:
* Support for all versions of Windows in use today: Vista, XP, 2003, 2000, Me, 98, 95, and NT 4.0. (No service packs are required.)
* Extensive support for installation of 64-bit applications on the 64-bit editions of Windows Vista, Windows XP, and Windows Server 2003. Both the x64 and Itanium architectures are supported. (On the Itanium architecture, Service Pack 1 is required to install in 64-bit mode.)
* Supports creation of a single EXE to install your program for easy online distribution. Disk spanning is also supported.
* Standard Windows 2000/XP-style wizard interface.
* Customizable setup types, e.g. Full, Minimal, Custom.
* Complete uninstall capabilities and more...
Changelog:
* On Windows Vista, [Run] section entries with the postinstall flag no longer inherit Setup"s elevated privileges by default, and instead now execute with the (normally non-elevated) credentials of the user that started Setup initially. (There are some exceptions; see the runasoriginaluser flag documentation for details.)
* Added new [Run] section flags: runascurrentuser and runasoriginaluser. These control which user credentials are used on Windows Vista when spawning processes. (runasoriginaluser is the default when the postinstall flag is used; runascurrentuser is the default otherwise.)
* Improved compression of x86 executable files. (This reduced the size of Inno Setup"s own installer by approximately 10 KB.)
* Added new [Files] section parameter: ExternalSize.
* Added new constant: {log}. Translates to the log file name, or an empty string if logging is not enabled.
* Added new [Files] and [Dirs] sections flags: setntfscompression and unsetntfscompression. These flags instruct Setup to enable or disable NTFS compression on the file or directory.
* Pascal Scripting:
- Added new ExecAsOriginalUser, ShellExecAsOriginalUser, and SetNTFSCompression support functions.
- Now supports new DLL loading flag loadwithalteredsearchpath to load DLLs with the Windows flag LOAD_WITH_ALTERED_SEARCH_PATH.
* The Setup loader now uses the original Setup EXE filename + .tmp as the filename for the extracted Setup executable instead of a name comprised of random letters and numbers, which may have seemed suspicious to firewall users.
* In a multilingual installation, Setup now waits until after the Select Language dialog is shown to display any error messages concerning the user"s Windows version or privilege level.
* Fix: On Windows Vista, AutoPlay wasn"t being suppressed when the user swapped out discs in a disk-spanned install.
* Fix: When the waituntilidle flag was used in the [UninstallRun] section, it behaved like waituntilterminated.
* Based on RemObjects Pascal Script SVN code revision 1045a.
* The uninstall program"s version is now 51.48.0.0.
