title: Cannot install ImportExcel Powershell module
body: <p>First, I would like to say that I'm a total beginner, so please try not to use to complexe words. I use Powershell V5 and I need to run the following line :</p>
  
  <pre><code>Install-Module ImportExcel -scope CurrentUser
  </code></pre>
  
  <p>But an error message appears</p>
  
  <blockquote>

    d'applet de commande, fonction, fichier de script ou  programme
    exécutable. Vérifiez l'orthographe du nom, ou si un chemin d'accès
    existe, vérifiez que le chemin d'accès est  correct et réessayez.</p>
