Wix Managed Bootstrapper 在卸载升级包时无法卸载 WtsApi32.dll

Question

我创建了一个托管引导程序 (wix v3.9.1208.0)，它的工作方式有点像 Visual studio/Resharper 安装程序，在这方面工作得很好：

安装时它会安装先决条件并安装或跳过您select从捆绑的可用应用程序列表中获得的内容。
如果你修改那么它会 uninstall/skip/install 你 selections.
卸载会删除所有非必备应用程序。

我的问题是在升级时。正在升级的应用程序安装没有问题，甚至前一个捆绑包的卸载也会在最后开始，但这是所有错误的地方。它到达我调用引导程序 InvokeShutdown 的 ApplyComplete 事件，然后它停止。我日志的最后几行到了这一点如下，最后是错误。

我查看了 procmon 以查看是否可以获得更多见解并发现这些是最后几个条目。在 dll 的日志条目被锁定之前，WtsApi32.dll 有一个待删除的删除。关机是否太早了？

如果我在 windows 资源管理器中尝试去那里，wtsapi32.dll 试图从中删除的包文件夹确实显示为访问被拒绝。

原来有人在我的自定义 BA 覆盖中注释掉了我的逻辑运行在某些情况下显示视图而不是其他情况。因此，当 Command.Display 被嵌入时，代码试图显示我的视图，因此我认为 dll 在关机时被锁定。哦，至少找到了原因！
