VS2013 + WDK8.1 加上虚拟机Windows 7，通过pipe com 1来连接，一直提示如下错误：
System.UnauthorizedAccessException: Access to the path is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.Pipes.NamedPipeClientStream.Connect(Int32 timeout)
at System.IO.Pipes.NamedPipeClientStream.Connect()
at Microsoft.DriverKit.DriverTestServices.WaitForRemoteExecute(String computerName)
at Microsoft.DriverKit.DriverTestServices.RemoteExecute(String computerName, RemoteExecuteCommand& remoteCommand)
at Microsoft.DriverKit.DriverTestResult.ResultRun()
copy DriverTesting这个文件夹已经成功，管道应该是通了的，但是在各个文件安装上应该有权限问题，但是我按照提示的错误log，在目标虚拟机上，一个一个进行安装，从新连接，还是会提示同样的错误。
