Hi Thor, Thanks for your reply which I appreciate. I am not sure as to the origin of the free preview, but the entire course is free and as such anything can be previewed. Since the installation of the software was the starting point of the entire course (as I wish to introduce Visual Studio 2017, for a reason of course, specifically for the course which is mentioned in the course title and there are dozens of other compiler's around) on which further course was designed, I think it just adds value to the course. Any serious learner is also expected to view the other introductory (talking heads) section to find the details of the course before putting his ratings/comments. All said and done, I will take the review with comments into account for further course designs. Thanks Kaushik
