Cannot Download macOS from App Store

I downloaded macOS High Sierra Installer (full) from App Store, but it claimed it was not a valid Installer when I tried to make a bootable USB drive. Now the App Store download page only offers Open option in menu, but does not offer Download option.

iMac, macOS 10.12

Thank you for your reply.


I had downloaded the installer, to the point at which it opened, (& I could Quit it), but it turns out it had not completely downloaded, as it was both smaller that it should be, and the associated .download file was still present, and indicated not fully downloaded.


So my question is: If the download is faulty, how do you download it again?
