The reason I wanted to stick with the 2017 version is because I have a few other people that have 2017 Sketchup Make (the free version) that I send sketchup drawings to so that they can view my drawings from all angles themselves, without me having to take multiple 2D shots and send to them. Using the documentation provided I am installing SketchupPro 2019.3 and copying over a activationinfo.txt into the appropriate \\ProgramData\\SketchUp\\SketchUp 2019 folder Doing this. (I am in a K-12 organization and we applied for a grant through TCEA and this is how the serial number and auth code were provided to me. Oh really, so it doesn’t sound like I’m going to have much luck getting 2017 Sketchup Pro version Record the User, Company, and Serial number EXACTLY as typographical errors will prevent you from upgrading successfully. I just recently received my serial number and auth code for Sketchup Pro.
