title: .loadby sos clr - specified module could not be found
body: <p>I am trying to get to the bottom of what the CLR exception that is in my dump file but I am having an issue trying to execute:</p>
  
  <pre class="lang-none prettyprint-override"><code>0:000&gt; .loadby sos clr

      "The specified module could not be found."

  <p>I tried to look at what is loaded and I see:</p>

  <p>And then as per suggestion from @Thomas Weller:</p>
  
  <pre class="lang-none prettyprint-override"><code>0:000&gt; lmf m clr
  Browse full module list
  start             end                 module name
  000007fe`f9fe0000 000007fe`fa980000   clr      C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll
  </code></pre>
  
  <p>The path (<code>C:\Windows\Microsoft.NET\Framework64\v4.0.30319</code>) exists on my PC and there's a <code>SOS.dll</code> inside.</p>
  
  <p>Additional information:</p>
  
  <ul>
  <li><code>ld clr; .reload /f</code> does not help</li>
  <li>I've not used <code>.cordll</code> to modify the CLR loading paths</li>
  <li><code>.load C:\Windows\Microsoft.NET\Framework64\v4.0.30319\SOS.dll</code> works, but it's longer to type</li>
  </ul>
  
  <p>Why is <code>.loadby sos clr</code> not working for me? (I just installed WinDbg from <a href="https://developer.microsoft.com/en-us/windows/hardware/windows-driver-kit" rel="nofollow noreferrer">https://developer.microsoft.com/en-us/windows/hardware/windows-driver-kit</a>) by selecting to install "Debugging Tools for Windows" from the installer)</p>
