I placed the dcraw.exe in the directory as you suggested but it doesn't work. I tried with these images https://code.google.com/p/rawtohdri/downloads/detail?name=Canon_CR2_2.zip&can=2&q= as well and I get the UnableToOpenBlob error anyway.
I tried doing dcraw.exe image.CR2 from the command line and it generates image.ppm in the same directory. But if you look at the exception it says 'C:/.../AppData/Local/Temp/magick-1096qq7lCu64cJT6.ppm': No such file or directory.
Oh, ok, I figured out! I had ImageMagick installed and dcraw was in the system path. So when trying to read an image, the dcraw used was the one from IM and not the one in my bin folder.
Thanks for you help
