It seems irrespective of size PDFCerator caanot handle MS-WORD .docx files. On my Windows 7 machine it gives an error msage:
Error No.: 53 (File not found: gsdll32.dll)
Modul: ModGsApi
Procedure: CallGS
Line: 502000
After saving to a .doc file PDFCreator works fine. Why the problem with new style .docx files?
