Install PDFCreator as NT Service using SC command

(1) Add PDFCreator to the exception list DEP
       Control Panel => System => Advanced system settings =>Advanced => Data Execution Prevention.

(2) Ge srvany.exe from the Windows Server 2003 Resource Kit (There are no Windows 2008 Server Resource Kit as of today)

(3) create the service with the sc command:
 
   sc create pdfcreator start= auto binPath= "C:\Program Files\oldResourceKitTools\srvany.exe" DisplayName= "PDFCreator" obj= DOMAIN\User password= password  
(Note that there is one space after Equal Sign)

(4) sc query pdfcreator

(5) Reg editing as in KB137890 :
 
1. Regedt32.exe locate   
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pdfcreator
2.Add Key.    
  Key Name: Parameters
  Class :<leave blank>
3.Select the Parameters key, Add Value.  
 Value Name: Application
 Data Type : REG_SZsc start
 String : <path>\<application.ext>
 
where <path>\<application.ext> is the drive and full path to the application executable including the extension (i.e., C:\PDFCreator\pdfcreator.exe)

Set up ghostscript PDL to convert xps to PDF

For 32 Bit:
Download binary e.g. ghostpdl-8.71-win32.zip http://www.ghostscript.com/releases/
unzip and find gswin32
command  gxps-871.exe -sDEVICE=pdfwrite -sOutputFile=33.pdf -dNOPAUSE tiger.xps

For 64 Bit

download ghostpdl-9.00.tar.gz  and get all the source
use VC++  nmake xps_msvc.mak to complike gxps.exe ( from 64 bit sdk prompt)
gxps -sDEVICE=pdfwrite -sOutputFile=77.pdf -sNOPAUSE tigger.xsp

CutePDF is a printer that convert any doc to PDF and can be programed in C#
(PopUp Dialog to save file). It uses ghostscript.
