I bought a 2016 Sketchup Pro license and was pleased that I could get Sketchup 2016 to run under wine in Ubuntu Linux!

However, the Sketchup "Add License" button doesn't work! Nothing happens when you press it.
The temporary license has run out, so I can't use it until this licensing problem is sorted out.

I have exactly the same problem with SU pro 2015 and Su pro 2016.
There are however no problems with installing my Su pro 2014 version.
I am running these version with play on linux on my ubuntu machine.
If somebody of the Sketchup team is reading this, please consider at least working together with the wine developers to make a working version for linux for the next release.

Does this help to solve your problem?
