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>\...)
