You must read and follow the directioins EXACTLY or ithe links will not work. You probably will also not be able to download any patches, but if you can find someone with a patched version you can copy their applicatioin folder and it should work if you've successfully installed the original version (but make sure you back up first).
Windows 7 itself ended its support nearly two years ago. It is difficult to continue using the old OS. You should purchase hardware that runs Windows 10 or later, and then use the current provided version.
