title: Mujoco installation, binaries not found
body: <p>I'm in trouble for installing mujoco.</p>
  <p>I folows the steps at <a href="https://github.com/openai/mujoco-py/issues/253" rel="nofollow noreferrer">https://github.com/openai/mujoco-py/issues/253</a>.</p>
  <p>Everything worked correctly, but when I had to run &quot;python examples\body_interaction.py&quot; I'm having an issue :</p>

  <p>This is how my .mujoco directory looks like:</p>
  <p><a href="https://i.stack.imgur.com/mOL6z.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mOL6z.png" alt="enter image description here" /></a></p>
  <p>And mujoco200 is the directory i downloaded from there: <a href="https://www.roboti.us/index.html" rel="nofollow noreferrer">https://www.roboti.us/index.html</a> for win64,</p>
  <p>This is how my Env variables looks like:</p>
  <p><a href="https://i.stack.imgur.com/1zDbR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1zDbR.png" alt="enter image description here" /></a></p>
  <p>To solve this, I tried to download &quot;mjpro131 win64&quot; from <a href="https://www.roboti.us/index.html" rel="nofollow noreferrer">there</a>, and add it to the env. variables using name &quot;MUJOCO_PY_MJPRO_PATH&quot;, but then it gave me an other error:</p>

  <p>Last line translation:</p>
  <pre><code>OSError: [WinError 193] %1 Is not a valid win32 application.

  <p>I Also tried with the win32 achive, but it gave me the exact same error.</p>
