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.
