Inno Setup 7.0.2 – free installer for Windows apps

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. It supports the disk spanning, full uninstall capabilities, customizable setup types, integrated file compression. Also includes support for installing shared files and OCX’s, and creation of Start Menu icons, INI entries, and registry entries.

This program places no arbitrary limits on how many files, shortcuts, registry entries, etc. that you may include in an installation. However, keep in mind that Inno Setup does need memory for each entry in a script. For example, roughly 120 bytes of memory is needed for each [Files] entry.

Inno Setup Key features:

• Extensive support for installation of 64-bit applications on the 64-bit editions of Windows. The x64, ARM64 and Itanium architectures are all supported.
• Extensive support for both administrative and non administrative installations.
• Supports creation of a single EXE to install your program for easy online distribution. Also supports the Disk spanning.
• Standard Windows 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/LZMA2 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.
• Support for multilingual installs, including right-to-left language support.
• Running other programs before, during or after install.
• Support for passworded and encrypted installs.
• Support for digitally signed installs and uninstalls, including dual signing (SHA1 & SHA256).
• Silent install and uninstall.
• Unicode installs.
• Integrated preprocessor option for advanced compile-time customization.
• Integrated Pascal scripting engine option for advanced run-time install and uninstall customization.
• Full source code is available from GitHub.
• Tiny footprint: only about 1.3 mB overhead with all features included.
• All features are fully documented.
• Used by Microsoft Visual Studio Code and Embarcardero Delphi.

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.

Changes in Inno Setup 7.0.2 (2026-07-13):

• Added new Security Measures help topic, which also includes a Supply-chain security section and links to our Verifying Inno Setup Downloads page.
  The security measures, the supply-chain security, and the download verification are not new, but they are now documented and linked in one place.
• Compilation will now fail with an error if an .iss/.isl file contains a byte value or sequence that is not valid in the file’s code page (character set). Previously, invalid bytes were interpreted as U+FFFD characters (the Unicode “replacement character”).
• Pascal Scripting: Improved documentation of support functions RegisterServer, RegisterTypeLibrary, IncrementSharedCount and ApplyPathRedirRules with updated explanations and examples.
• Fixes:
  • ISCC: Reading the script from standard input by specifying - as the script name is now documented again in the help file. Such a script is now assumed to be UTF-8 encoded.
  • When a custom style is active, the Do this for the next conflicts checkbox in the File exists, confirm overwrite and Keep newer file? task dialogs could start checked instead of unchecked (broken since custom styles were introduced in 6.6.0).
  • In previous 7.0 releases, when a 64-bit installer performed a 32-bit DLL registration or shared file reference count operation on a file under {sys}, a SysWOW64 path was erroneously used instead of a System32 path.
  • Setup no longer clears the read-only attribute of files and directories matching an [InstallDelete] entry’s wildcard during its initial checks, before installation has started (broken since 5.5.0).
  • In Japanese, Korean, and Chinese, Setup no longer shows the accelerator key as literal text, such as “(&R)”, in a few places.
  • Extracting a .cab archive no longer always fails with an error (broken since its introduction in 6.5.0).
  • Pascal Scripting: Selected TNewCheckListBox items with a custom ItemFontStyle or SubItemFontStyle no longer become unreadable after the list loses focus (broken since its introduction in 6.2.0). Thanks to Sergii Leonov for contributing this fix.
• Updated the 7-Zip and LZMA SDK source code used by Inno Setup to the latest versions.
• Added official Lithuanian, Simplified Chinese and Traditional Chinese translations.
• Improvements and corrections to all other official translations.

Changes in Inno Setup 6.7.3 (2026-05-26):

• Improved the Wine RichEdit workaround added in 6.7.2 to prevent a startup delay when very large texts are used in combination with a dark custom wizard style.
• Fix: Example script PowerShell.iss now uses an absolute path to load powershell.exe, for security reasons. If you used the demonstrated technique in your own scripts, you should make the same changes.
• ISPP:
  • Fix: A user defined function which has no parameters compiles again (broken in 6.7.2). Example: #define MyAppName() "My Program".
  • Added new predefined variable SysPath.
