title: Unable to start program "C:\Program Files\dotnet\dotnet.exe"
body: <p>I've installed .NET Core 1.0.1 to use with VS 2015 Update 3 and I'm running as Administrator (on Windows 8.1 x64).</p>
  
  <p>If I create <em>any</em> .NET Core project, be it console or web and attempt to <em>run</em> it Visual Studio then comes up with an error:</p>
  
  <p><a href="https://i.stack.imgur.com/9UHuU.png"><img src="https://i.stack.imgur.com/9UHuU.png" alt="enter image description here"></a></p>
  
  <p>However I'm unable to ascertain why. VS builds it fine and I can run it from the CLI. I can also run Core fine through VSCode.</p>
  
  <p>I've tried:</p>
  
  <ul>
  <li>Deleting <code>project.lock.json</code></li>
  <li>Deleting the <code>.vs</code> folder</li>
  <li>Repairing the .NET Core install</li>
  <li>Repairing the VS 2015 install</li>
  <li>Uninstalling and reinstalling .NET Core/SDK/Tooling &amp; VS</li>
  <li>Rebooting</li>
  </ul>
  
  <p>And it still refuses to work!</p>
  
  <p>I've raised this on the Core Tooling GitHub as well as can be seen <a href="https://github.com/aspnet/Tooling/issues/807">here</a> but as yet we're all a little stumped.</p>
