That means the file you're trying to download doesn't exist. If you click on a button or a link to initiate the download that contains that bad URL. Three things you can do:
1. Guess what the right URL is and type that in the address bar of your browser
2. Report the error to the webmaster of the site you download from so they can correct it.
3. Find another download location.
