Hello,
i would be really happy to use this pludin in SU 2017 - but was not working
Error Loading File Fredo6_FredoTools.rb
Error: #<LoadError: cannot load such file -- Fredo6_!LibFredo6.rb>
C:/Program Files/SketchUp/SketchUp 2017/Tools/RubyStdLib/rubygems/core_ext/kernel_require.rb:54:in require' C:/Program Files/SketchUp/SketchUp 2017/Tools/RubyStdLib/rubygems/core_ext/kernel_require.rb:54:in require'
C:/Users/Richie/AppData/Roaming/SketchUp/SketchUp 2017/SketchUp/Plugins/Fredo6_FredoTools.rb:25:in `<top (required)>'

either i was trying SU 2013 - plugin was installed, but Report on Area (which i need) was not working ((
so i tried it on SU8 ...but there i couldnt even find the way how to instal plugin (!!)

oh i am just poor unhappy user
