title: Failed to Start Process with Commandline VSIISExeLauncher.exe in IIS 10.0
body: <p>Thursday night, I was working on a project built in ASP.NET Core 2.1 (being prepared for ASP.NET Core 2.2) running on my local IIS 10.0 (<em>not</em> IIS Express) and was able to run it without any issue. Friday morning, after heading into the office, I was met with the following error every time I try to run my solution in Visual Studio:</p>
  
  <ul>
  <li><strong>Unable to start process C:\Program Files (x86)\dotnet\dotnet.exe. The web server request failed with status code 502, Bad Gateway. The full response has been written to [file_name].html.</strong></li>
  </ul>
  
  <p>When I open the [file_name].html, I'm given the response:</p>
  
  <ul>
  <li><strong>HTTP Error 502.5 - ANCM Out-Of-Process Startup Failure</strong></li>
  </ul>
  
  <p>When I open the Event Viewer, I'm given the response:</p>
  
  <ul>
  <li><strong>Application 'MACHINE/WEBROOT/APPHOST/DEFAULT WEB SITE/[Path]' with physical root '[Path]' failed to start process with commandline '[Path]\bin\IISSupport\VSIISExeLauncher.exe -argFile IISExeLauncherArgs.txt', ErrorCode = '0x800700c1' : 0.</strong></li>
  </ul>
