title: Visual Studio 2017 Installer is "Unable to download installation files"
body: <p>I've just finished talking to the "Microsoft Support Chat" and he told me to post this here (i can't post it on the developercommunity forums because i need to click a button in the installer which isn't there at that stage).</p>
  
  <p>When I'm trying to run the VS Enterprise 2017 installer (or any other edition) the installer cancels with the error message: "Unable to download installation files. Check your internet connection and try again."</p>
  
  <p>What I tried so far: </p>
  
  <ul>
  <li><p>Running as Administrator</p></li>
  <li><p>Downloading the installer with a different browser</p></li>
  <li><p>Using the --layout option to download files first (same error message, no files downloaded)</p></li>
  <li><p>Installing the certificates</p></li>
  <li><p>Using the --update option before running the installer regularly</p></li>
  <li><p>Running the Windows 10 Windows Update Troubleshooter (couldn't identify the problem)</p></li>
  <li><p>Disabling Bitdefender Antivirus</p></li>
  <li><p>Multiple Reboots/Re-Downloads</p></li>
  </ul>
  
  <p>One more thing that might be helpful is that quite a while back when i was installing "Cyber Ghost VPN" on the same machine i had trouble connecting using that application because a windows service that should've been active wasn't running.</p>
  
  <p>Also I would've included the Logs from running the vscollect tool but i can't seem to figure out how to attach a file here. Do i have to upload it somewhere else and include the link or is there a way i can just attach the file here?</p>
