Hi,
it is possible to contol PDFCreator via COM to influcense the parameters for the the conversion, but it is still a converter, mainly to convert postscript into PDF. If you are getting this error in a 2.x version, please send the loggin level to “trace” in the debug section of the application settings, perform the action which causes the error and send the resulting log to support(at)pdfforge.org or post it here and we will have a look at it.
Best regards,
Robin
