 Inno Setup
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, 2008,   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. Both the x64 and Itanium architectures are   supported. (On the Itanium architecture, Service Pack 1 or later is   required on Windows Server 2003 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.
* 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.
* Support for passworded and encrypted installs.
* Silent install and uninstall.
* Full source code is available (Borland Delphi 2.0-5.0).

Change Log:
* Compiler IDE changes:
- The editor component has been changed from SynEdit to Scintilla.
- Autocompletion support has been added to all sections except for [Messages], [CustomMessages], and [Code].
- Brace highlighting has been added to all sections.
- Syntax errors are now underlined during editing. (Support for the [Code] section is limited.)
- Constants are now highlighted.
- Variable-pitch fonts may now be selected as the editor font.
- ISPP inline directives ({#...}) are now consistently highlighted in all contexts.
- Zooming is now supported.
- Added new options: Word wrap (default: off), Auto indent mode   (default: on), Show indentation guides (default: off), Invoke   autocomplete automatically (default: on), Underline syntax errors   (default: on), and Use tab character (default: off).
* Setup now instructs edit controls which are used to input a file or   folder name to use AutoComplete to help complete file system paths.
* On disk space checks, Setup now queries the nearest volume mount point rather than the root.
* The default directory and Start Menu folder names specified via the   /DIR=, /GROUP=, and /LOADINF= command line parameters now may include an   "expand:" prefix which instructs Setup to expand any constants in the   name. For example: /DIR="expand:{pf}\My Program".
* Pascal Scripting changes:
- TNewProgressBar: Added new Style and State properties. See the CodeClasses.iss example script for an example.
- TBitmapImage: Added new OnClick and OnDblClick properties. See the
CodeClasses.iss example script for an example.
* QuickStart Pack changes:
- All ISPP functions that take filenames have been changed to interpret   the filenames as relative to SourcePath instead of the current  directory  with the exception of Exec, ReadIni, and WriteIni, as they  already have  their own established handling of relative filenames.
- ISPP directive #include no longer searches the current directory.
* Dropped Itanium-specific 64-bit support for the [Files] section's   regtypelib flag and the [Registry] section's Permissions parameter.   These features depended on an Itanium-specific "helper" binary, which we   no longer have the ability to test or build. (x64 support for these   features is unaffected.)
* Updated bzip2 library to version 1.0.6.
* Minor tweaks.
