Inno Setup is a tool, designed for creating professional installation programs, which can run on all Windows platforms between Windows 2000 and Windows 8 (this includes business versions of this OS, with 32 and 64-bit versions also fully supported). Although this open-source program can be used by anyone for free, Inno Setup is really stable and offers more features than most of its similar paid alternatives. 

This made it incredibly popular with worldwide audience who demanded access to perfect tools, wide OS support and advanced features such as complete uninstall tools, disk spanning, single EXE installers, support for multiple binaries inside a single package, INI/Registry management, integrated scripting engine (based on Pascal), passworded and encrypted packages, support for multiple compression algorithms, multilingual install interfaces and much more.

The first version of Inno Setup was created by developer Jordan Russell in IDE software package Embarcadero Delphi in distant 1997. From that moment, this free software received countless updates and streamlining of a visual interface that can today easily be used by both users who have very little technical knowledge about software development and seasoned professionals. The installers created with Inno can be of the conventional “wizard” type, can create shortcuts, launch or delete files, and can be password-protected or encrypted. The interface is not very intuitive, but various front-ends have been developed to make working with this product easier.

InnoSetup is a 100% free application that can be even used commercially, although its original developer is open to receive donations that are funding active development of this popular developer tool.

What's new in this version:

Compiler IDE changes:
- Added mouseover tooltips for all Pascal Scripting support functions and class members showing their prototype. Always shows all classes' members instead of just those of the current object's class.
- Autocompletion lists now use the same font as the editor
- Fix: When the IDE was started for the first time on a system with a DPI setting over 100%, the editor's initial font size was larger than expected

Other changes:
- {reg:...} constants can now also embed REG_DWORD-type registry values
- Fix: In 6.4.0, using "Shift+" in a HotKey parameter in the [Icons] section didn't work and required "Shift" instead, so for example "Ctrl+ShiftM" instead of "Ctrl+Shift+M"
- Fix: In 6.4.0, a custom form shown using [Code] didn't have a taskbar button if Setup's wizard was not visible at the time
- Added official Arabic translation
- Some minor tweaks and improvements
