You have to go to System Preferences->Security->General and allow you Mac to run software downloaded from “Anywhere”.
After you run it once it assumes you now “trust” that app.
Alternatively to the suggestion to change the security control panel (you can
leave it in the “App store…” setting) and right-click (or control-click) on any new application and choose “Open” — then it should give you
the option to run it even though it isn’t signed by a developer.
