Free installer for Windows programs.
Features:
* Support for all 32-bit Windows versions in use today -- Windows 95, 98, 2000, 2003, XP, Me, NT 4.0 SP6.
* 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.
* Installation of files:
Includes integrated support for "deflate", bzip2, and 7-Zip LZMA file compression. The installer has the ability to compare file version info, replace in-use files, use shared file counting, register DLL/OCX's and type libraries, and install fonts.
* Creation of shortcuts anywhere, including in the Start Menu and on the desktop.
* Creation of registry and .INI entries.
* Integrated Pascal scripting engine.
* Support for multilingual installs.
* Silent install and uninstall.
* Full source code is available (Borland Delphi 2.0-5.0).
What's New:
* 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.
