It's when I download it from the browser. It gets maybe 30% done and then it fails. I've tried to google it, and the only thing I could find that might be the problem is that I needed to update Windows, which I've spent all day doing. I've tried it again and it's the same problem. I currently don't have any antivirus software running, so I don't think that's what's causing it. Is this maybe a problem with Firefox?
