.rar files from unreal learning not opening as they should

I am relatively new to unreal engine and reviewing blueprints before starting on any real projects. I downloaded the .rar files from the box website, and opened them as an earlier tutorial suggested; by using the “browse” feature to open it as a project. When I do this the engine will either crash or tell me that its not an unreal project. If anyone could tell me how I could get this working that would be great.
