HI Fredo ,
Have not been able to run the libfredo6 plugin successfully on Pro 2021
, tried reinstalling sketchup and re-down loading the plugin as per all the post feedback i could find on the web . Ps also no security access issues just to mention .

I receive the following error message .

Error Loading File Fredo6_!LibFredo6.rb
Error: #<NameError: uninitialized constant LibFredo6_Loader::LibFredo6>
C:/Users/Christo/AppData/Roaming/SketchUp/SketchUp 2021/SketchUp/Plugins/Fredo6_!LibFredo6.rb:67:in process' C:/Users/Christo/AppData/Roaming/SketchUp/SketchUp 2021/SketchUp/Plugins/Fredo6_!LibFredo6.rb:74:in module:LibFredo6_Loader'
C:/Users/Christo/AppData/Roaming/SketchUp/SketchUp 2021/SketchUp/Plugins/Fredo6_!LibFredo6.rb:30:in `<top (required)>'

Any assistance would be appreciated .
