[后续] 使用 CtrlGetText() 从 InstallShield 对话框中提取值，将该数据传递给我的 dll 以包含在我的应用程序配置文件中。生成的 .config 文件条目包含大量“�”序列。尝试使用 InstallScript 清理这些内容的尝试效果不佳。最终不得不通过将 XmlDocument 翻转为字符串，在字符串上执行 .Replace("�", "") 将它们加载到 XmlDocument 中（以确保它有效），然后保存它，从而在 dll 中清理它们. InstallShield！= 太棒了。[/跟进]
XML 文件更改似乎不是一个好的方向，因此我编写了一个自定义操作，该操作在安装该功能后触发。自定义操作调用一个托管程序集，该程序集通过 xml 文件将更改应用到应用程序 .config 文件。
自定义操作

MessageBox("Error Loading" + SUPPORTDIR ^ CO_APPCONFIG_DLL + ": " + Err.Number + " " + Err.Description, INFORMATION);
abort;
endcatch;
