Comment 3 for bug 722920

I'm also encountering this problem; using GS 9.04 and ImageMagick-6.7.3-7-Q16 on Win7 x64. convert logo: logo.pdf works perfectly, but PDF import in Whyteboard always returns a "Ensure Ghostscript is installed" error. I attempted to run your provided command:

"C:\Program Files (x86)\ImageMagick-6.7.3-Q16\convert.exe" -density 200 "C:\Users\Public\Downloads\test.pdf" -resample 88 -unsharp 0x.5 -trim +repage -bordercolor white -border 20 "C:\Users\Public\Downloads\test.png"

and IM returned the following error:

convert.exe: `%s' (%d) "gswin32c.exe" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r200x200" "-sOutputFile=C:/Users/Charles/AppData/Local/Temp/magick-CZnnzH8M--0000001" "-fC:/Users/Charles/AppData/Local/Temp/magick-HmcrQeFp" "-fC:/Users/Charles/AppData/Local/Temp/magick-5-dZDDd8" @ error/utility.c/SystemCommand/1903.
convert.exe: Postscript delegate failed `C:\Users\Public\Downloads\test.pdf': No such file or directory @ error/pdf.c/ReadPDFImage/661.
convert.exe: missing an image filename `C:\Users\Public\Downloads\test.png' @ error/convert.c/ConvertImageCommand/3016.

I've ensured that the target PDF file exists in the specified directory, and that the Public Downloads folder is publicly-writable.

Thanks for your hard work, and hope this sheds some light on the issue!
