What to do if Conversion Attempt Failed?
If you see a Conversion dialog “Fatal Error” or, “PDF3D Conversion Engine has stopped…” or “Windows has detected a problem…”, this may be caused by insufficient memory resources, or an file format problem. To discover more, on the Conversion tab enable “Extended Log” and try again. More information and messages leading up to the failure may be helpful. Run the Windows Task Manager with “Performance” and “Processes” tab open and try conversion again. Check if the progress to see if an unexpectedly high memory resource is demanded by the conversion. If possible arrange to send the input data model file to support for analysis and advice, along with a screenshot of expected content.
