Delete "Install macOS Mojave" from the Applications folder. Download again while in Safe Mode.

Same thing here. I have a mid-2012 MacBook Pro and Mojave is as far up the OS chain as it can go; currently running High Sierra. The AppStore Mojave installer downloads but instead of launching, up pops a message that this copy of the installer is damaged and cannot be used to install the OS.
