我正在创建一个 WiX 安装程序，我希望允许用户选择安装目录的路径以及数据目录。我在我的代码中添加了两个InstallDirDlg，并命名为一个Custom_Dir 和另一个Custom_DirData。
在 Custom_DirData 中，我没有使用 WIXUI_INSTALLDIR 属性，而是使用了 DATALOCATION 属性，该属性是在安装开始时在 appsearch 中设置的。
当我运行 msi 时，Custom_Dir 工作正常。但是，当我进入 Custom_DirData 对话框时，只要按浏览或下一步，就会弹出 2343 错误消息。
这是它在日志中所说的：
DEBUG: Error 2343: Specified path is empty.
我可以在日志文件中看到之前设置的这些属性：
PROPERTY CHANGE: Adding DATALOCATION property. Its value is 'C:\Remindex Local Data\'.
PROPERTY CHANGE: Adding _BrowseProperty property. Its value is 'C:\Remindex Local Data\'.
所以我不太确定它在说什么路径。以防万一您需要一些额外的信息，以下是 UI 代码中的三个相关对话框：

任何建议将不胜感激。
