I have downloaded the installer twice for Mojave. Where can I get an undamaged copy?

Is The App Store showing 'Open' at the Mojave download page.
If so and you get "this copy of Mojave is damaged", it really means the App Store
has detected a copy of Install macOS Mojave.app in your Applications folder.
Locate it, move it to the Trash, empty the Trash.
Connect your mac to your router via cable rather than rely on WiFi.
Restart your mac, go back to the App Store Mojave download page,
it should now say 'Get' or 'Download'.
Do not use the mac while it is downloading or any devices that share
the same internet connection.
