problem with pdf

[ssrahurk]

Neither of the commands convert or identify work with pdf.. sometimes they do work when used with the pdf's generated by imagemagick but that too not always..

convert 5.pdf 5.tiff
this is the error -

convert: `%s': %s "gswin32c.exe" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -d
NOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGridFitTT=0 "-sDEVI

convert: Postscript delegate failed `5.pdf': No such file or directory.
convert: missing an image filename `5.tiff'.

it gives a similar errror with identify

identify 5.pdf

Which release of Ghostscript are you using? Make sure it is a modern release. ImageMagick delegates PDF conversion to Ghostscript. If Ghostscript fails to interpret your PDF, ImageMagick will fail as well.
