在所有版本的IE中都有很多设置&Windows，这可能会导致用户试图运行xbap应用程序的问题，特别是在完全信任模式下。
在过去的一年里，我似乎收集了一长串这样的案例。然而，我被一个异常所困扰，这个异常发生在我的一个系统上的一个用户身上，我希望这里有人能给我指出正确的方向。此应用程序运行在所有使用版本的windows, IE6 -> IE9，没有问题，所以没有任何错误的部署/xbap它自己。用户得到下面的errorlog/stacktrace。你们有人遇到过这种模糊的痕迹吗，知道这可能是什么问题吗?此用户正在运行IE8 &支W7 .
用户已在受信任的根机构中安装了适当的证书&值得信赖的出版商。有问题的网站已被添加到受信任网站列表中。IE中已启用Xbap。
url, publickeys, appname等已被打乱。

我应该在"解决"这个问题时回答这个问题的。
在上面的例子中，客户端计算机有一个问题，更换磁盘，重新安装操作系统等解决了这个问题。
问题是什么，仍然是一个谜;)
