Inno Setup是一个强大而灵活的工具，用于为Windows应用程序创建专业的软件安装程序。Inno Setup自1997年首次发布以来，一直是开发人员的信赖之选。该工具因其简单性和高效性而受到高度赞扬，使开发人员能够轻松构建全面的安装包。

Inno Setup 的一个突出特点是支持所有版本的 Windows，包括最新版本。它提供广泛的自定义选项，使开发者能够根据特定需求定制安装过程。脚本引擎功能强大，能够处理复杂的安装任务和条件操作。

Inno Setup还支持多语言安装，确保软件能够覆盖全球受众。该工具包括集成文件压缩、密码保护和支持数字签名等功能，提高了安装包的安全性和完整性。

Inno Setup是开源的，提供开发人员灵活性以修改和扩展软件以满足其独特需求。活跃的社区和全面的文档使其易于入门并找到常见挑战的解决方案。凭借其易用性、强大功能和多功能性，Inno Setup仍然是开发人员创建可靠且用户友好的安装程序的首选。

关键特性：

• 多种安装类型：根据用户选择创建完整或最小安装。
• 自定义脚本：使用Pascal脚本进行量身定制的安装过程。
• 多语言支持：轻松用不同语言创建安装程序。
• 磁盘跨越：将安装程序拆分到多个磁盘上以支持大型应用程序。
• 文件压缩：使用内置的压缩选项减小安装程序的大小。
• 自动卸载程序：生成一个卸载程序以便轻松卸载软件。
• 数字签名：支持对安装程序进行签名以增强安全性。
• 良好的文档：有很好的文档记录，并有强大的社区支持以提供帮助和资源。

• /LOG: Now logs INI entries. Also improved logging of icon entries.
• Added new [Setup] section directive: Output, which defaults to yes. If set to no the Setup Compiler will only check the script for errors and skip creating setup files.
• Console-mode compiler (ISCC) changes:

1. Added new command line parameters /DO and /EO. These can be used to disable or enable output, overriding the Output directive.
2. Added new command line parameter /Qp. Can be used to enable quiet compile while still displaying progress. Contributed by KngStr via GitHub.
3. ISCC now automatically specifies any Sign Tools configured using the IDE, eliminating the need to specify these using the /S command line parameter. Also contributed by KngStr via GitHub.

• Pascal Scripting changes:

1. Added new function CurrentSourceFileName, which returns the source file name of the [Files] entry that is currently being processed. The returned name may include constants. Note: Do not attempt to call this function from outside a Check, BeforeInstall or AfterInstall event function belonging to a [Files] entry with the external flag.
2. The already-existing StrToFloat and FloatToStr functions are now documented.
3. Strings and numbers are now highlighted. Based on contribution by maldoinc via GitHub.
4. Unicode Inno Setup: Added new class TStringStream.

• Inno Setup Preprocessor (ISPP) changes:

1. Added function DeleteFileNow.
2. Added 64-bit support to function ReadReg.

• Added official Scottish Gaelic and Turkish translations.
• Fix: [Setup] section directive UsePreviousLanguage was not working when Setup was running in 64-bit mode.
• Unicode [Code] based on RemObjects Pascal Script Git commit 97eefc260b41ba51328d95b4ed43669f38655720.
• Various documentation improvements. Contributed by jogo- via GitHub.
