I have followed advise from other posts and deleted the previously downloaded Installer, emptied trash, and dowloaded again and continue to get the same error. "This copy of the install macos mojave application is damaged and can‘t be used to install macos."
Thanks,
Apparently I was missing some Security updates and it appears that after installing all updates the Installer worked correctly.
Restart in Safe Mode(press Shift), and if possible, use a wired Internet connection.
