我们安装了 .NET Framework 开发人员工具，专门用于 .NET 4+ 和 VS 2010-2013。安装程序包括应自动安装的 MS Help Viewer 格式的随附帮助文件。
我们的安装是使用 Inno Setup 构建的，这里是用于安装电子文档的安装脚本的相应部分：

如您所见，我们尝试为每个可能的 VS 语言环境安装文档。但是，如果特定语言环境不存在，则会显示以下错误框：
此页面描述了如何避免此消息的方法之一（请参阅“缺少文件错误：访问外语目录”部分。）但是，这是我们不能在自动产品安装中使用的手动解决方案。
如果我们需要从安装包中安装 Help Viewer 文档，如何避免这个问题？
