我正在使用teamcity运行一些测试用例。它正在成功保存文本文件中的数据，但是当我尝试从同一位置读取该数据时，它会发出以下错误
SetUp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-C000-000000000046}失败 由于以下错误：800704a6。在 WatiN.Core.IE.CreateNewIEAndGoToUri（Uri uri，LogonDialogHandler logonDialogHandler，Boolean createInNewProcess）at WatiN.Core.IE..ctor（）
并用System.String[]替换保存的数据。还试图给用户所有的permisssions但仍然无法解决它。请帮忙。
我也启用了大多数IE8设置。知道是什么导致了这个
以下是构建日志

不确定这是否已经解决，但我在用C＃编写的另外两个不同的测试装置1中遇到了同样的错误，另一个用VB.NET编写。
对于C＃fixture我需要做的就是解决这个问题，当我创建一个新的WatIn.IE实例时，我将第二个参数添加到：IE var ie = new IE（url， true ） “true”告诉WatIn“createInNewProcess”，它在新进程中打开下一个IE。
然而，由于某种原因，这对于用VB.NET编写的测试夹具不起作用。 对于这个fixture，我不得不在我们的一个C＃库中调用一个方法来强制每个Tests“TearDown”方法中的IE闭包。 以下C＃代码实现了这一诀窍：
public static void CloseInternetExplorers()
{
var processes = from process in Process.GetProcesses()
where process.ProcessName == "iexplore"
select process;
foreach (var process in processes)
{
while (!process.HasExited)
{
process.Kill();
process.WaitForExit();
}
}
}
