  <p><strong>Tried:</strong>  Still the same problem</p>
  
  <p>I double checked the folder location and it <strong>matches</strong></p>
  
  <blockquote>
    <p>C:\Users\me\Documents\jupyter_notebooks</p>
  </blockquote>
  
  <p><strong>I also tried:</strong> It install and runs, able to open and read but no changes allowed</p>
  
  <pre><code>pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

  <p><strong>System:</strong></p>
  
  <ul>
  <li>Windows 10</li>
  <li>Python environment: 2.7 &amp; 3.5</li>
  <li>package manager: pip / pip3</li>
  </ul>
  
  <p><strong>Possible contributing factors:</strong>
  Made some system changes two days ago, and since the problem started. I believe is a permission issue. I recall deselecting a "permissions check box" for executing scripts. but it only seemed to affect Jupyter</p>
  
  <p><strong>Not acceptable solutions:</strong></p>
  
  <p>"Try Anaconda", "Reinstall windows" - the system was working fine and continues to work, with the exception of Jupyter enability to make changes</p>
  
  <p>Thank you in advance</p>
