I use PDF Creator 0.9.2 under Windows XP Home. If I print in an Office-Program or an other program via PDF Creator and I am not in administrator-mode I get an Error 481 Modul: modMain Procedure: StartProgram Line 51040
This doesn't occure, when the PDF Creator PrintMonitor is already open. But if You open the PrintMonitor after the Error 481 occurred, You will find all files, which You tried to print, in the spoolfile. When You restart to print all files will be converted to PDF.
