This Error 404 File problem occurs because the cumulative security updates for Internet Explorer that are reference in the “Symptoms” section of this article change the base URLs of JavaScript functions to the direct scripting sites.

If the JavaScript functions use relative URLs to open Web pages, this change will cause the URLs of the Web pages to be incorrect and you will receive the error 404 file or directory not found message that is list in the “Symptoms” section of this article.

Solution for Error 404 File or Directory Not Found:

A 404 error is an HTTP status code that means that the page you were try to reach on a website couldn’t be create on their server.

Technically, an Error 404 is a client-side error, implying that the error is your mistake, either because you type the URL in wrong or the page has been moved or removed from the website and you should have known.

Solution Process:

Another possibility is if a website has moved a page or resource but did so without redirecting the old URL to the new one. When that happens, you’ll receive a 404 error instead  of being automatically route to the new page.

Microsoft IIS web servers sometimes give more specific information about the cause of 404 Not Found errors by suffixing a number after the 404 as in HTTP Error 404.3 – Not Found which means MIME type restriction.

Retry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.

The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for.
