Generating true 16 bit HDR image (no tone mapping)

It work realy great, at least with my sample pics.
Problem is, that I can’t run batch in cmd. Command >hdrmerge --batch -a -g 10 --no-crop *.cr2 do nothing. I put my cr2 raw pictures in same folder with hdrmerge.exe. -g 10 is for gap.
hdrmerge --batch -a --no-crop IMG_1018.CD2 IMG_1019.CR IMG_1019.CR work, but program treminate in unusual way withot HDR file creation. I’m using HDRMerge 0.5.0
