I am trying to install the 2015 Kitchen-Click plug in but I get a message saying I need to let the application have access to my computer files. Is this a common thing with extensiions or plug ins? I am leary about giving access to my computer files to someone I don’t know.
Yes, it’s normal to see the message.
It appears each time you install a SketchUp .RBZ plugin via Preferences > Extensions > Install Extension.
Download and install extensions only from trusted sources.
I.e. Trimble SketchUp Extension Warehouse, SketchUcation PluginStore or other reliable known authors.
