Every time I try to download the update for macOS Mojave I get an error has occured validating the installer data. The download is either damaged or incomplete. Redownlload the installer and try again. How do I do this?
MacBook Pro 15", macOS 10.13
Check your Applications Folder for "Install macOS Mojave.app". If it is there, drag it to the Trash. Enter your administrative password when prompted to trash it. Download a fresh copy of the macOS Mojave installer. This issue has happened to more than a few people. You need to trash the damaged copy before you can download a fresh copy.

If you have 3rd party antivirus software installed, remove it.
I don't have third party antivirus software. but thank you, for this suggestion.
Open Console in Applications>Utilities & see if there are any clues or repeating messages when this happens.
Thank you.
