>> For PDF's Ghostscript (for the last ten years - and now with python). Pyvox is a Python extension module for processing volume images, particularly medical images. Using open source means you have the source - if the guy stops supporting or updating - do it yourself. Not that hard - believe me.

>No there is a 64bit Ghostscript (has been for a long time). Works well for me? We convert all the invoices into PDF for emails. We also have several reports in excel that converted to PDF. Last year we send out over 40,000 PDF's - we archive them on to DVD's.

I think it's the PostScript driver that's used to generate .ps files for GhostScript, that Adobe didn't update since 1991, and won't install on 64.

Anyway, I've found a different tool (the TextDynamic ocx) which does this quite fast, and doesn't require Word to print out a .doc into a .ps - and mind you, Word was the source of the problem. Office automation is actively fought against, by none other but Microsoft.
