ImageMagick cannot handle PostScript and PDF files itself and by its own. For this it uses a third party software called Ghostscript as a 'delegate'.

Has your Windows system Ghostscript installed properly? Or is not installed at all?

Try to download and install the latest version from here.

Probably you'd get a different error message if the problem is caused by a missing Ghostscript installation. But your error is:

D:\RealDocs.pptx.pdf': No such file or directory 
@ pdf.c/ReadPDFImage/634.convert.exe: missing an image filename `d:\hello.jpg' 

This could mean that the user account you run this command under does not have permission to write to the root of the D: drive.

To test this, you could run the conversion command in a cmd.exe window in a slightly modified way:

 "C:\Program Files\ImageMagick-6.5.8-Q16\convert.exe" ^
      "D:\RealDocs.pptx.pdf" ^
      "%userprofile%\hello.jpg"

(On Windows XP, %userprofile% usually points to c:\documents and settings\<your username>\...)
