Missing PDFCREAT.PPD when installing v1.0.1 non-virtual PC's

If I install this product on a Virtual PC (WinXP - SP3 - 32Bit) it works fine. If Install it on a non-Virtual networked PC (WinXP - SP3 - 32Bit), the file PDFCREAT.PPD is not installed. Only PDFCREAT.BPD is installed and I get an error message that the print driver is not installed. If I manually copy PDFCREAT.PPD to C:\\WIndows\\sytem32\\spool\\drivers\\w32x80\\3, it works fine.

 

Any ideas?
