title: Visual Studio 2017 fails to install offline with "Unable to download installation files"
body: <p>So I've created an offline installed of VS 2017 Community on my laptop using this command:</p>
  
  <blockquote>
    <p><strong>vs_community.exe</strong> --layout "D:\Downloads\VS Community 2017" --lang en-US --add Microsoft.VisualStudio.Component.CoreEditor Component.WebSocket Microsoft.VisualStudio.Workload.ManagedDesktop Microsoft.VisualStudio.Workload.NetCrossPlat Microsoft.VisualStudio.Workload.NetCoreTools Microsoft.VisualStudio.Workload.Node Microsoft.VisualStudio.Component.TypeScript.2.0</p>
  </blockquote>
  
  <p>When I transfer the setup files onto my corporate PC (which is behind a firewall) and run the "vs_community.exe" setup file, all I get is this error. There's no way to bypass the corporate firewall or to make exceptions. How do I install VS 2017 offline? Am I missing something here?</p>

  <p><strong>Edit:</strong> I have installed VS 2017 on my laptop keeping the internet connection active. Then when I disconnect the internet on my laptop and try installing again, the installer launches! So perhaps there are some dependencies missing on my corporate PC that are now installed on my laptop? </p>
  
  <p><strong>Edit:</strong> The above command installs .NET, .NET core, Xamarin, Node.js, TypeScript and C++ for Mobile. The total downloaded size is 13.2 GB.</p>
