We were having problems installing the extension on Sketchup Pro 2016. Could not find any mention of the problem we were having.
The error popped up after restarting Sketchup:
Error: #<LoadError: 126: The specified module could not be found. - c:/users/boardroom/appdata/roaming/sketchup/sketchup 2016/sketchup/plugins/enscape/Bin64/EnscapeSketchupPluginHost.so>

We tried many things, different profiles, reinstalling Sketchup, but found that installing the Visual Studio 2017 Community package windows and dotnet components allowed Enscape to run. Have not determined which of the components are specifically fixing the issue.
hope this helps. T
