Downloading MacOS High Sierra 10.13 on iMac

When I go to the App Store to download High Sierra 10.13, I get this message: This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS. What do I need to do?

Open your Applications folder and look for Install macOS High Sierra.app, move it to the Trash, empty the Trash.

Connect your mac to your router via cable, Restart your mac go back to the App Store and download High Sierra.
