      Issue

      When Inventor Server is used to open a document within a powerJobs Processor job the job terminates with the error "class not registered" and shows the following in the log file:

         bei Inventor.DataIO.WriteDataToFile(String Format, String FileName)
         bei powerJobs.Application.Inventor.Exports.DataIoExport.Execute()

      You can register the necessary keys by installing Inventor View and starting it one time
