I it did say the same on MC edge as well. I tried again, and now I got through! How do I get my installer to use MC edge?
The problem doesn't happen here on MS Edge. The installer will always use the correct URL, no matter what your browser you use, I only made an *example* to let you TEST the URL, but if you really cannot find the URL with MS Edge ( are you SURE you are typing the correct and complete URL, which starts http, NOT https ? ), then the problem must be your ISP possibly filtering the site, or possibly the antivirus.
You can try the Offline installer, posted in the Sticky thread named "Offline Installer", that will at least give you the latest code, but for the latest updates for models and operators, you must fix your connection problem, since those are not contained in the Offline installer.
