Inno Setup 5.3.3 Beta

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. Features include a wizard interface, creation of a single EXE for easy online distribution, support for disk spanning, full uninstall capabilities, customizable setup types, integrated file compression, support for installing shared files and OCX’s, and creation of Start Menu icons, INI entries, and registry entries.
Inno Setup places no arbitrary limits on how many files, shortcuts, registry entries, etc. that you may include in an installation.

However, keep in mind that Setup does need memory for each entry in a script. For example, roughly 120 bytes of memory is needed for each [Files] entry. A typical Inno Setup installation running on Windows NT/2000/XP/2003 does not require administrative or “power user” privileges.

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).

Changes in version 5.3.3 (2009-08-01):
* [Setup] section directives VersionInfoProductVersion now sets the binary product version value instead of the textual product version value.
* Added new [Setup] section directive: VersionInfoProductTextVersion, which sets the textual product version value. Its default value is VersionInfoProductVersion if set, else VersionInfoVersion.
* [Setup] section directives DisableDirPage and DisableProgramGroupPage can now be set to auto. If they are, at startup Setup will look in the registry to see if the same application is already installed, and if so, it will hide the pages automatically.
* Pascal Scripting changes:
o WizardForm.PrevAppDir is now available and returns the directory of the previous installation. Returns an empty string if there’s no previous installation or if UsePreviousAppDir is set to no or if Uninstallable was previously set to no.
o While running any PrepareToInstall event function Setup now displays the Preparing to Install wizard page instead of the Ready to Install page and disables itself.
* Added the Windows 7 “compatibility” section to the various manifest resources used by Inno Setup.
* Documentation improvements.

The Inno Setup QuickStart Pack includes Inno Setup itself and additionally includes options to install third-party add-ons such as the ISTool script editor and Inno Setup Preprocessor. These add-ons are not official and are not required for general usage, but make Inno Setup easier to use.
