Wix Toolset v4托管Bootstrapper应用创建失败求助（错误0x80131508）

多日寻找Wix Toolset v4的Managed Bootstrapper Application可用示例，大多都是v3版本。目前遇到错误代码0x80131508，日志提示无法创建、加载托管引导程序应用。

安装程序包含基于WPF（.NET Framework）的自定义UI、Wix Toolset v4构建的MSI，通过Bundle生成exe文件。日志报错如下：

Error 0x80131508: Failed to create the bootstrapper application.
Error 0x80131508: Failed to create the managed bootstrapper application.
Error 0x80131508: Failed to create BA.
Error 0x80131508: Failed to load BA.
Error 0x80131508: Failed while running
