Yes. There would have been quite a few complaints had it been in maintenance mode for over a week. Also just checked it for you, just in case.
Please check whether maybe your firewall or antivirus program blocks the installer from accessing the internet. This is the most likely issue when the web installer shows ‘Download Error’. May also be a router or a (company) firewall in your network.
The second option is that it may just be a temporary network error somewhere between our server and you. In that case simply waiting a little bit and then trying again may solve the issue.
Mine was working fine just a few days ago. Now i presume it’s trying to update, saying “Preparing to download” and then “Download Error”. I have no antivirus or anti malware program other than windows defender. And it’s off too.
