TypeScript compile error in Visual Studio 2015

Question

Installed Visual Studio 2015, added a TypeScript file to an existing project folder. File looks like this (from a Telerik sample):

interface Book {
    title: string;
    author: string;
    bookInfo: () => string;
}

var b: Book = {
    title: 'Moby Dick',
    author: 'Herman Melville',
    bookInfo: function () {
        return this.title + " by : " + this.author;
    }
}

var book = b.bookInfo();
alert(book);

Upon building the solution, I got an error:

Severity: Error Description: Automation server can't create object
Project: Project1
File: VSTSC

Went into Developer Command Prompt for VS2015 and ran tsc just to see what comes back:

C:\Tfs\Project1\Scripts\app>tsc tsc.js(703, 13) JavaScript runtime error: Automation server can't create object

Same message as the one in Visual Studio 2015.

Unsure what is the problem with the TypeScript compiler. I did make sure I installed TypeScript 1.5.4 via Tools > Extensions and Updates.

What shall my next step be?

Yes, I looked there before and per link, it only supports Windows 2000 and XP. Am running Windows 7 SP1.

I have no idea... try to compile your code with gulp or something like this. Also try to post your problem on official github thread

The default tsc on windows (non node version) uses IE's JavaScript engine to execute the JavaScript.

From here:

The simple solution may be to reset your IE security settings to the default Medium-high setting

Also disable any third party active x components you installed in IE.
