Where can I find the installer for macOS Mojave? I'm currently running High Sierra.
The installer in the App Store is damaged and can't be used.
The support page only seems to feature updates to Mojave, not Mojave https://support.apple.com/downloads/mojave
Delete any copy of "Install macOS Mojave" from the Applications folder, then try while in Safe Mode.

No joy, deleted the install tried again, didn't work.
Went to App store on second Mac, downloaded the install app, copied it to my first Mac, and then failed again.
In all cases a dialog appears saying
"This copy of the install macOS Mojave.app application is damaged, and can't be used to install macOS".
Looks like an issue with the application file on the App store.
Got it working finally.
I installed an outstanding High Sierra security update, after which the same installer app worked first time.
The error dialog for the install was obviously misleading.
Thanks for your time and help.
Did you try while in Safe Mode?
If you have access to an Ehthernet connection you should try that as well.
You're welcome
