title: Docker: could not read CA certificate
body: <p>I installed Docker on Windows 10 Pro and I can't get it to work.</p>
  
  <p>When I try to run hello-world I get</p>
  
  <pre><code>could not read CA certificate 
  </code></pre>
  
  <p>It's looking for the certificates in the machine/machines/default . However that folder didn't exist.</p>
  
  <p>I created a machine called "default" (which created the above mentioned folder) but that didn't help.</p>
  
  <p>Before that I created another machine called "dev" which seems to have certificates, but that doesn't seem to be helping either.</p>
  
  <p>Also there are certificate files in machine/machines - I don't know if I should somehow point Docker to look in that folder (instead of machine/machines/default) ?</p>
  
  <p>I'm pretty new to Docker so I might be missing something. However I've been at this all day, read the Docker documentation, tried plenty of solutions and similar answers but nothing seems to be working. </p>
