PDF Automated call from a program.

I use PDF Creator from my application, and want to save automatically the PDF into a specific directory.

This has been working fine, and now it seems that i cannot reprint the same filename. Also it is impossible to delete it, W8 gives me a : Action can't be completed because file open in another program. But i can delete it from DOS Cmd "del blabla.pdf" without problem. It seems to me that it remains open, not for the file system, but only in the Registry parameters.

To allow automatic saving, i use to change the registry that way:

UseAutosave = 1

OpenOutputFile = 0

AutosaveDirectory = qwaqwa

LastsaveDirectory = qwaqwa

AutosaveFilename = blabla

SaveFilename = blabla

the file is saved correctly, and i can open it without problem, but cannot delete it from W8 or reprint with the same name and location.

For resetting, i just put spaces into AutosaveDirectory, LastsaveDirectory, AutosaveFilename and SaveFilename,.
