Inno Setup是一个免费的安装制作软件，它既有 适合新手的脚本向导，又有良好的脚本编辑环境，能 够快速制作出标准Windows2000风格的安装界面，足以 完成一般的安装任务，在新版本版中软件加入了对多语 言的支持，这个功能的实现相较于NSIS来得简单多了， 推荐大家使用新的版本。在新版本中我自行按软件的关 联程序注册的健值编写的注册表关联文件的编写例子， 其中我还增加了一个源软件没有的“新建 Inno Setup 脚本 .iss”健值，希望该例子能对大家编写注册表脚 本有所帮助，其实该软件也支持识别系统分别安装的不 同的文件具体见例子吧(安装时注意选择是否使用安装 软件关联注册表或使用软件本身关联注册表[二选一， 如果全部安装也没问题，只是让大家试试这个功能罢了])！ 在这次的更新中我打包了一个ISX Download DLL，就是 ISTool 网站上提供的一个可以使Inno Setup生成的安装 文件在安装时从网上下载组件的功能(不必装 ISTool 也能实现) 具体代码自己看ISX Download DLL自带的例子。
