BIRT shows always the same error-message while using the option preview on Knime Reporting.
" org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report. "
Other preview options (ppt, odp etc.) doesn't work as well. Only "View Report as HTML" works without error-message but it will not be shown all images.
I use a 64-bit version.
