I have only sketchup, without any plugin, and it closes after a few minutes…
When i uninstall sketchup, and later i install sketchup, the folders in the directories: C:\ProgramData\SketchUp\SketchUp 2016 and C:\Users\your user name\AppData\Roaming\SketchUp\SketchUp 2016 are different…, in occasions the folder sketchup into sketchup 2016 don´t appear…, and between one installation and other installation there are folders that appear or not…
