Where to download latest XP compatible version of Sketchup?

Thank you DanRathbun. I found a link and downloaded V 14.1.1282 and started the lessons. So far, so good.

However, I do not have a License. And, when I went to Trimble, Inc. 1. I could not find out how to purchase one (save for 2017 version) and, 2. The price was $695.

I cannot afford seven hundred dollars to play with this program. I thought there was a ‘free’ license version for non-commercial users.

Is there?
