LCFM Native requires Advanced Tools to be turned on in FileMaker. To do this open up Preferences in FileMaker Pro, and click Use Advanced Tools.
If you have turned on "Use advanced tools" and you are still getting an error that LCFM Native cannot use Advanced Tools, the issue may be the language you are running FileMaker in. If you are not using English, you will need to switch your language to English before LCFM Native can work. Please see this article for instructions on doing this.
