Error logged while trying to run Robot Test in IE11 - WebDriverException: 404 - File or directory not found
<p>I'm trying to execute certain tests in Robot framework - tests that are working fine with Chrome using the Chrome Driver.</p>

<p>Once execution starts, I get an exception in the command prompt and execution stops without the browser even opening (Attaching the log.html file screenshot and snippet)</p>

<pre><code>Suite setup failed:

<p>Been stuck with this issue for the past 4 days. I tried searching many forums and pages on the internet with all possible combinations of keywords, but no luck. :(</p>

<p>Please, tell me how I can proceed with this issue.</p>

<p>Thanks.</p>

<p>I don't have a separate Test Setup. I just use a Suite Setup as below: </p>

<pre><code>*** Settings ***
Documentation Execution: Performance Validations 
Resource    Performance_Tests_Resource.txt 
Suite Setup    Open Web Browser 
Suite Teardown     Close Browser
</code></pre>

<p>where my <em>Open Web Browser</em> keyword has the following: </p>

<pre><code>Open Web Browser 
    Open Browser    ${URLGoogle}    ${BROWSER} 
    Maximize Browser Window
</code></pre>

<p>and I pass ${BROWSER} as a command line variable</p>

<p><strong>EDIT</strong> - The problem seems to be with IE11, because if I uninstall the IE11 and IE10 updates and try to start execution with IE8, it works just fine!</p>

<blockquote>
  <p>For IE 11 only, you will need to set a registry entry on the target computer so that the driver can maintain a connection to the instance of Internet Explorer it creates. For 32-bit Windows installations, the key you must examine in the registry editor is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. For 64-bit Windows installations, the key is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BFCACHE. Please note that the FEATURE_BFCACHE subkey may or may not be present, and should be created if it is not present. Important: Inside this key, create a DWORD value named iexplore.exe with the value of 0.</p>
