Unit testing 由于以下错误而失败：尝试从teamcity中的文本文件读取数据时发生800704a6

我正在使用teamcity运行一些测试用例。它成功地将数据保存在文本文件中，但当我尝试从同一位置读取该数据时，它给出了以下错误

安装方法失败。System.Runtime.InteropServices.COMException： 使用CLSID创建COM组件的实例 来自IClassFactory的{0002DF01-0000-0000-C000-0000000000 46}失败 由于以下错误：800704a6。在 WatiN.Core.IE.CreateNewIEAndGoToUri（Uri，LogonDialogHandler logonDialogHandler，布尔值createInNewProcess）位于 WatiN.Core.IE..ctor（）

并将保存的数据替换为

System.String[]

。还尝试向用户提供所有权限，但仍然无法修复。请帮忙

我还启用了大多数IE8设置。你知道这是什么原因吗

以下是构建日志
