title: Can't run classic ASP page on Windows 10 even after installing ASP support via "Turn Windows features on or off"
body: <p>I get this error:</p>
  <blockquote>
  <p>An error occurred on the server when processing the URL. Please contact the system administrator.</p>
  <p>If you are the system administrator please click <a href="https://docs.microsoft.com/en-us/iis/application-frameworks/running-classic-asp-applications-on-iis-7-and-iis-8/classic-asp-not-installed-by-default-on-iis" rel="nofollow noreferrer">here</a> to find out more about this error.</p>
  </blockquote>
  <p>But I already installed classic ASP support on my IIS; why would I be getting this error? I tried restarting IIS and that didn't help; just in case the error message came from the application itself, I searched for it but didn't find it in the code anywhere.</p>
