Hi,
I’ve got this issue too, I use Sketchup make 2016 and the installer doesn’t detect my Sketchup. I run skp as administrator, same thing for vray, but still not detect the version for the installation.
Maybe it don’t work with make?
You could try SketchUp Make v2017 and see if that makes a difference - Download All | SketchUp. Chaos Group doesn’t differentiate between Pro and Make so hard to say if that’s the problem.
Can you confirm that you meet all the other requirements for install? *also reminder that SketchUp Make is licensed for non-commercial purposes only so if you work professionally or sell your work in any way, make sure to upgrade to SketchUp 2020 Pro. Thanks!
SketchUp version 2016 was, I think, the last one with separate 32- and 64-bit versions, so make sure that you are running a 64-bit Windows and 64-bit SketchUp. Later versions are 64-bit only.
Thanks for clarifying @Anssi. I’m assuming it’s a 32-bit version of SU 2016 which is causing the problem and Chaos Group requires 64 (as noted by the parenthesis) above.
