To run the example project then you must have the following plugins from Einhugur Software installed:

   * CoreClasses - Latest version.
   * TypeLib - Latest version.
   
   * StyleGrid 8.8.5 or later. (If intending to use the
     StyleGridExcelExporter part)


If one of those is missing then REALbasic will complain that there is a error in the protected class.
