Yup, this is a mistake. Depending on how you get the link to the file, if you enter the URL into your browser you'll get a direct download, but when RHDN Bot downloads the file, it is served a download page instead. This is why I keep telling everyone to use "Copy public link" in explorer's context menu. You have to change "https" to "http", but other than that, the link always works the way it's supposed to.
chetchaka, when you spot a mistake, you can actually fix it yourself. There is an edit button on the page. RHDN is like a moderated wiki. It is community-maintained. You can edit most content yourself. We're just here to rubber-stamp it.
