body: <p>I'm using a powershell script to download and execute a file, but since some time I go I get a could not create ssl/tsl secure channel.</p>
  
  <pre><code>$down = New-Object System.Net.WebClient; 
  $url = 'url'; 
  $file = 'file';
  $down.DownloadFile($url,$file); 
  $exec = New-Object -com shell.application; 
  $exec.shellexecute($file); 
  exit; 
  </code></pre>
