title: vagrant up not working on windows
body: <p>I am following the official vagrant documentation at 
  <a href="https://docs.vagrantup.com/v2/getting-started/index.html" rel="noreferrer">https://docs.vagrantup.com/v2/getting-started/index.html</a></p>
  
  <p>I have installed vagrant and virtual box on Windows 10 64-bit processor. 
  After running these commands on command prompt I get:</p>
  
  <pre><code>vagrant init hashicorp/precise32
  vagrant up
  </code></pre>
  
  <p>errors as shown below:
  Bringing machine 'default' up with 'virtualbox' provider...
  ==> default: Box 'hashicorp/precise32' could not be found. Attempting to find and install...
      default: Box Provider: virtualbox
      default: Box Version: >= 0
  The box 'hashicorp/precise32' could not be found or
  could not be accessed in the remote catalog. If this is a private
  box on HashiCorp's Atlas, please verify you're logged in via
  <code>vagrant login</code>. Also, please double-check the name. The expanded
  URL and error message are shown below:</p>
  
  <p>URL: ["<a href="https://atlas.hashicorp.com/hashicorp/precise32" rel="noreferrer">https://atlas.hashicorp.com/hashicorp/precise32</a>"]
  Error: SSL certificate problem: unable to get local issuer certificate
  More details here: <a href="http://curl.haxx.se/docs/sslcerts.html" rel="noreferrer">http://curl.haxx.se/docs/sslcerts.html</a></p>
  
  <p>curl performs SSL certificate verification by default, using a "bundle"
   of Certificate Authority (CA) public keys (CA certs). If the default
   bundle file isn't adequate, you can specify an alternate file
   using the --cacert option.
  If this HTTPS server uses a certificate signed by a CA represented in
   the bundle, the certificate verification probably failed due to a
   problem with the certificate (it might be expired, or the name might
   not match the domain name in the URL).
  If you'd like to turn off curl's verification of the certificate, use
   the -k (or --insecure) option.</p>
  
  <p>How do I fix this error ?</p>
