  <p>When I run <strong><code>anaconda-navigator</code></strong> from the Prompt, I receive this:</p>
  
  <pre><code>Traceback (most recent call last):

  During handling of the above exception, another exception occurred:

  <p>Then I tried <strong><code>conda install pyside</code></strong> :</p>
  
  <pre><code>Solving environment: failed
  
  UnsatisfiableError: The following specifications were found to be in conflict:

  <p>Thanks in advance.</p>
