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，它的工作原理非常好：

安装时，它会安装先决条件，并安装或跳过您从捆绑的可用应用程序列表中选择的内容。
如果您修改则会卸载/跳过/安装您的选择。
卸载会删除所有非必备应用程序。

我的问题是我升级时的问题。正在升级的应用程序安装没有任何问题，甚至卸载以前的捆绑包也会在最后启动，但这是一切都出错的地方。它进入ApplyComplete事件，我调用bootstrappers InvokeShutdown，然后停止。我的日志的最后几行到达这一点如下，最后的错误。

我看了一下procmon，看看我是否可以获得更多的洞察力，并发现这些是最后几个条目。在锁定dll的日志条目之前，WtsApi32.dll有一个删除暂挂。关机是否试图过早发生？

如果我尝试在Windows资源管理器中运行，那么尝试删除wtsapi32.dll的包文件夹会显示为拒绝访问。

事实证明有人在我的自定义BA覆盖Run中注释了我的逻辑，以在某些场景中显示视图而不是其他场景。因此，当Command.Display嵌入时，代码试图显示我的视图，因此我认为dll在关闭时被锁定。哦，至少找到了原因！

在卸载升级的捆绑包时，Wix Managed Bootstrapper无法卸载WtsApi32.dll
