after eval month was up with SketchUp 2016 I was still able to use the tool. with 2017 I get blocked at the startup screen with “Licensed To: SkectchUp Pro 2017 Trial User, Expired”. the only option provided is to exit or add a new license.
Will this be fixed or is there a workaround so I can continue with me designs?
I suspect that you did not install Make with its free Pro trial [when it reverts to Make at the end], but rather that you installed Pro - which expires after the trial, and then needs to be licensed or replaced by a new installation of Make…
You have two options.
Buy a Pro license - which is needed if you intend to use SketchUp commercially.
Download and install the Make version - which has a slightly reduced set of tools, that are regarded as only necessary for Pro users - and remember that Make is only for personal/non-commercial use…
