Hi,
From your error message, error 404 generally means whenever someone asks for a page that’s simply not
available on your site. The reason for this is that there may be a link on your site that was wrong or the page
might have been recently removed from the site. As there is no web page to display, the web server sends a
page that simply says "404 Page not found".
Did you get this error when you download or install process?
