title: Can't install Spyder 4.1.4 after using Python3.6 in Anaconda
body: <p>I need to open Spyder with Python3.6 because of compatibility issues while trying to import the cv2 module. I'm using Windows 10.</p>
  <hr />
  <p><em><strong>NOTE:</strong> Alternative solution below</em></p>
  <p>I didn't manage to do it the way it's specified in this post. I encountered the following errors:</p>

  </ul>
  <p>These two pages might be useful for those looking to solve this problem the way I first tried (specified below this note).</p>
  <br>
  <p>The way <strong>I</strong> solved it:</p>
  <p>Instead, in order to use Spyder with Python 3.6, in Spyder I went to: <strong>'Tools' &gt; 'Preferences' &gt; 'Python interpreter' &gt; 'Use the following interpreter:'</strong>, where I pasted the route of my Python 3.6 executable (should look like something similar to <code>C:\Users\user_name\AppData\Local\Programs\Python\Python36\python.exe</code>).</p>
  <p>The next time I executed Spyder, It was running on Python 3.6 flawlessly.</p>

  <p>An answer in this useful <a href="https://stackoverflow.com/questions/43592879/how-to-change-python-version-in-anaconda-spyder">post</a> suggested running the following code in the Anaconda Prompt to change the version:</p>
  <pre><code>conda create -n py36 python=3.6  #for version 3.6
  activate py36
  </code></pre>
  <p>Which seemed to work, as now Anaconda lets me run 'py36' in 'Applications':</p>

  <p>But when I try to install Spyder 4.1.4 after changing to 'py36', the 'Install' button doesn't do much. A blue downloading bar appears, but once it finishes downloading whatever and the bar disappears, the 'Install' button never actually updates to 'Launch':</p>

  <p>The Anaconda version i'm using is:</p>
  <pre><code># packages in environment at C:\Anaconda3:
  #
  # Name                    Version                   Build  Channel
  anaconda                  2020.07                  py37_0
  anaconda-client           1.7.2                    py37_0
  anaconda-navigator        1.9.12                   py37_0
  anaconda-project          0.8.4                      py_0
  </code></pre>
  <p>Thank you very much.</p>

  <p><strong>EDIT:</strong> as user Arjun Muraleedharan suggested, I tried installing Spyder through the Anaconda prompt:</p>
  <pre class="lang-py prettyprint-override"><code>conda activate py36
  conda install spyder
  </code></pre>
  <p>But i got this error at the end of a long list of newly installed packages:</p>
  <pre class="lang-py prettyprint-override"><code>ERROR conda.core.link:_execute(700): An error occurred while installing package 'defaults::icu-58.2-ha925a31_3'.
  Rolling back transaction: done
  
  [Errno 13] Permission denied: 'C:\\Anaconda3\\envs\\py36\\Library\\bin\\icudt58.dll'
  ()
  </code></pre>
  <p>I tried running the Anaconda prompt as an administrator and it gave me the same error.</p>
