as Guillermo pointed out above.
That is, make a folder (directory) at the root level of your machine (C: ) called "dcraw" and then drop the dcraw executable in there. Just go the the Start menu> My computer> C: drive and make a new folder called "dcraw". Copy the dcraw executable into that folder.
Then go to the command line (the DOS prompt: Start>All programs>Accessories>Command Prompt) and navigate to the dcraw directory you just created and installed dcraw in - type:
and hit return - then type:
at the command line prompt and hit return - dcraw should spit out all of the usage options and command line flags - this means your machine is executing dcraw. If you are not familiar with the command line and issuing command line, err, commands, then maybe google that to see what I am talking about. I am a Mac user, so I am tapping into some old school knowledge residing in a dusty back corner of my brain (but really, has DOS changed in 20 years?).
