IntelliJ IDEA - typescript support - wrong syntax highlighting (or wrong ts-compiler in use)

I use latest IntelliJ IDEA (14.0.3) with (embedded) TypeScript/JS Support.

I Downloaded this angular-route.d.ts file to put to my project.

And the IDE shows me the highlighting, that that syntax is wrong.

I use Using tsc v1.4.1 ts-compiler for my project. (not sure if IDE is aware of it though).

Q: How to know what v of typescript compiler IDE uses? And how to make that ts-file to be valid?

I've read this official doc, but must be I missed something. As I understand the IDE should use that compiler I've installed as nmp package.

My project consists of package.json, GruntFile.js etc.. files - nodejs-like project.

In overal the stuff from ts-files are resolved.. Like I can see and navigate to that file

 function config($routeProvider: IRouteProvider): void {
        $routeProvider
            .when('/area11/stuff/newstuff', {
                template: '<div>New Stuff</div>',
                controller: (): void => {},
                controllerAs: 'vm'
            });
    }

So I can see/navigate to 'IRouteProvider' (which is defined in that highlighting file) from the IDE. This the project itself is set.. Just that little 'disappointment' with highlighting.
