JQuery-File-Upload 404 Error on Delete

I installed JQuery-File-Upload (and Backload) using NUGET into my VS2013 MVC 4.5.1 project.

The file upload works great and I successfully uploaded 3 files.

However, when I attempt to delete any of the files, nothing appears to happen on the page and Fiddler reports a 404 error.

Moreover, all the files exist and the folder and files within them have been set to EVERYONE with full control.

Also note, the message below specifies a path for backload's handler, but, the path doesn't exist ... should it?

C:\Projects\AustinTexasKarate\Web\Backload\UploadHandler doesn't exist.

Below are the results from Fiddler.

Note the error code: 0x80070002.

Does anyone know why delete doesn't work on my system or could provide clues? Did I miss something?

HTTP Error 404.0 - Not Found

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Most likely causes: •The directory or file specified does not exist on the Web server. •The URL contains a typographical error. •A custom filter or module, such as URLScan, restricts access to the file.

Things you can try: •Create the content on the Web server. •Review the browser URL. •Check the failed request tracing log and see which module is calling SetStatus. For more information, click here.

Per the Backload FAQ, you can tweak your Web.config to enable DELETEs without 404ing:

<system.webServer>
  <handlers accessPolicy="Read, Write, Execute">
      <remove name="WebDAV" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
