Sketchup 8

Hi, I was currently using the free version of Sketchup 8 (probably downloaded 5 years ago), however my computer has just died. Can someone please help me with what I need to download onto my new computer so that I can open / use the old designs I started?

Apologies, I am not the most tech savvy person, but enjoyed playing with the Sketchup program (on a basic level)

Your help is appreciated.

SketchUp Make 2017 is the latest available version free for non-commercial use (unless you count the web based version).
