IEDriverServer.exe is architected as a small, simple executable file that has a .dll with the real code for the IE driver embedded as a resource inside the .exe. To make use of this .dll, the executable has to extract the .dll somewhere so it can call the Windows <code>LoadLibrary</code> API to load and subsequently execute the code of the .dll. By default, that extraction is done into the temp directory. Without generating a log file to look into the issue, we can surmise that the .dll either isn't getting extracted properly, or once extracted, that the call to <code>LoadLibrary</code> failed.

Fortunately, the IE driver provides a workaround for this issue. If you pass <code>--extract-path="path\to\extract\dll\to"</code> as a command-line argument to IEDriverServer.exe, you will be able to explicitly specify which directory to use for the extraction. See the documentation for your language bindings to see how to have this command-line argument passed programmatically.

For instance, making this work for Java, the code would look like the following:

<pre><code>// WARNING: Entirely untested code below! Was written from memory without
// the benefit of an IDE. May not work correctly or even compile without
// modification.
// Assume "location" is a properly instantiated java.io.File containing
// the location of IEDriverServer.exe.
InternetExplorerDriverService service = new InternetExplorerDriverService.Builder()
 .withExtractPath(location)
 .build();
WebDriver driver = new InternetExplorerDriver(service);
</code></pre>

Another alternative might be to manually launch IEDriverServer.exe, and use your language bindings' <code>RemoteWebDriver</code> class to connect to it. That means you're responsible for the lifetime of the executable process, but it might be a way for you to get the behavior you're looking for.

blocks|key|2465563|text|我实际上遇到了一个类似的问题，它无法解压到临时目录，我所做的就是进入IEDriver解压DLL的文件夹，并删除了该文件夹中与Selenium相关的所有内容。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2465564|所以对我来说，它是C:\Users\usnm\AppData\Local\Temp，有很多像webdriver_blahblah120398405.tmp这样的文件，还有很多命名类似的文件夹。当我把它们全部移除后，我的程序又开始工作了。因此，对于您来说，它应该是C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp|2465565|当然，我们的错误略有不同(我使用的是Selenium+2.33)。我的错误是“提取失败”，而不是“加载失败”。|2465566|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I actually had a similar problem, where it couldn't extract to the temp directory, what I did was I went into the folder where IEDriver extracts the DLL, and deleted everything in that folder related to Selenium.

So for me it was C:\Users\usnm\AppData\Local\Temp, and there were a lot of files like webdriver_blahblah120398405.tmp, and a lot of folders similarly named. When I removed them all, my program started working again. So for you it'd be C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp

Of course our errors are slightly different (and I'm using Selenium 2.33). My error was "failed to extract", not "failed to load"

blocks|key|5814509|text|在某些系统中，防病毒软件或其他保护软件会阻止运行exe文件，在这种情况下，会阻止从临时文件夹加载dll库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5814510|在启动selenium节点时，添加一个额外的参数并指定当前目录的提取路径(确保当前目录可由用户写入，并且不需要提升的权限)。例如，如果您的节点位于C：\+IEDriverServer.exe，则|5814511|java+-jar+selenium-server-standalone.jar+-role+node+.....+-Dwebdriver.ie.driver.extractpath=C:\node|code-block|syntax|javascript|5814512|这应该可以解决这个问题。|5814513|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In some systems antivirus or other protection software prevent running exe files or in this case loading dll library from temp folder.

when starting your selenium node add an extra parameter and specify extract path to current dir (make sure current dir is writable by your user and does not require elevated privileges). For example if your IEDriverServer.exe is located in C:\node then

<pre><code>java -jar selenium-server-standalone.jar -role node ..... -Dwebdriver.ie.driver.extractpath=C:\node
</code></pre>

this should fix the problem.

blocks|key|2472703|text|按照答案2，这是做这件事的确切方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2472704|File+extractPath=new+File("c://your//file//todllextracts");
InternetExplorerDriverService+service+=+new+InternetExplorerDriverService.Builder().withExtractPath(extractPath).build();

Following the answer 2, this is the exact way to do it:

<pre><code>File extractPath=new File("c://your//file//todllextracts");
InternetExplorerDriverService service = new InternetExplorerDriverService.Builder().withExtractPath(extractPath).build();

driver = new InternetExplorerDriver(service);
</code></pre>

I'm testing our application using Selenium WebDriver 2.25 on different versions of Windows Explorer, which means running the test on different machines.

While testing the application with IE 8 works fine, I get an odd error when trying to run the test on the workstation with IE7. It's running Windows XP Service Pack 2 loaded with Java 6. When I try to run the IEDriverServer_Win32 executable, I get the following error:

<pre><code>Failed to load the library from temp directory: C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp
</code></pre>

What am I missing?
