从 这里<更新到 64 位的 IEDriverServer 3.9 后/a>，尝试使用 IE(版本:11.0.9600.17842，Win8.1)运行任何测试时出现以下异常.有谁知道如何解决这个问题，还是我应该降级回 3.8?
After updating to IEDriverServer 3.9 for 64-bit from here, I'm getting the following exception when trying to run any tests with IE (version: 11.0.9600.17842, Win8.1). Does anyone know how to get around this, or should I just downgrade back to 3.8?
OpenQA.Selenium.WebDriverException : 响应为空的异常向远程 WebDriver 服务器发送 HTTP 请求时抛出网址 http://localhost:53379/session.
OpenQA.Selenium.WebDriverException : A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://localhost:53379/session.
异常的状态是ReceiveFailure，消息是:底层连接是关闭:接收时发生意外错误.---->
The status of the exception was ReceiveFailure, and the message was: The underlying connection was closed: An unexpected error occurred on a receive. ---->
System.Net.WebException:底层连接已关闭:一个接收时发生意外错误.----> System.IO.IOException:无法从传输连接读取数据:现有连接被远程主机强行关闭.---->System.Net.Sockets.SocketException :现有连接是被远程主机强行关闭 TearDown :System.NullReferenceException:对象引用未设置为对象的实例.

使用 IEDriverServer 3.9.0.0 for Windows 64-bit from http://selenium-release.storage.googleapis.com 我可以使用 IEDriverServer_x64_3.9.0 重现该问题.
Using IEDriverServer 3.9.0.0 for Windows 64-bit from http://selenium-release.storage.googleapis.com I am able to reproduce the issue with IEDriverServer_x64_3.9.0.

虽然使用 IEDriverServer_Win32_3.9.0 的快速测试没有显示任何错误.虽然 IEDriverServer_Win32_3.9.0 和 IEDriverServer_x64_3.9.0 已发布，但从未明确推送/发布在下载 标签的 seleniumhq.org 页面.
Though a quick test with IEDriverServer_Win32_3.9.0 doesn't shows any error.
Though IEDriverServer_Win32_3.9.0 and IEDriverServer_x64_3.9.0 are put up but was never explicitly pushed/published to be available on the Download tab of seleniumhq.org page.
CHANGELOGIEDriverServer.exe 中明确提到了以下免责声明:
The CHANGELOG of IEDriverServer.exe clearly mentions the following disclaimer :
The "major" and "minor" fields are synchronized to releases of the Selenium
project. Changes in the "build" field indicate interim releases made publicly

Additionally, the CHANGELOG of IEDriverServer.exe v3.9.0.1 mentions the following disclaimer :
Finally, there is every chance that, despite all efforts to the contrary,
it's possible that there are new regressions introduced by this change.
Multiple test suites have been run using this change, and none have
failed thus far due to the changes herein. Claims that this change is
causing a specific failure should be accompanied by a full test case, or
issues reported against this change will be summarily closed.
