High Sierra installation file corrupted?

Hello. I am trying to install OS X 10.13.6 from 10.12.6 on a Mac mini. I have located the link in App Store but when try and install I am getting a message saying "This copy of the Install macOS High Sierra application is damaged, and can‘t be used to install macOS." Any help with this would be greatly appreciated.

Mac mini, macOS 10.12

Link to High Sierra installation files - https://support.apple.com/downloads/highsierra

Have you tried deleting the installation file in the applications directory before rebooting into safe mode and then downloading the installer again?

Thanks for your response! I am not sure where to delete the installation file it may have tried to download. I don't see it has downloaded anything apart from the error message. I rebooted into safe mode and tried to install but the same message came up again. Any and or all help greatly appreciated.
