The VCB Calc tool is installed like all other SketchUp® plugins.
The download zip file below contains one file, vcb_calc.rb, and a folder named "VCBCalc" containing additional files and a folder.
To install (or overwrite a previous installation), download and unzip (expand) the .zip file below. Copy the content of the expanded file into SketchUp®'s "plugins" folder.
Download and unzip (expand) this .zip file: vcb_calc_1_1.zip (41kb) [v 1.1 - Updated 2011-02-12. Now includes Spanish (ES) translation.]

Thanks to the generosity of Max Coppoletta of Quarr-IT, a toolbar icon is included.
Thanks also to Christophe Plassais for providing the FR translation and Defisto... xD! for the ES translation.
