I have a macmini (late 2014) with OS 19.13.6. Want to upgrade to Mojave.

I have tried to download mojave and it generates a file called "install macOS Mojave.app"

I get: "This copy of the Install macOS Mojave.app application is damaged, and can‘t be used to install macOS" Tried several time with same outcome.

I don't want to use Catalina as it will break a required program on this machine (no upgrade available and won't be available).
