    jimmy. you need to open a cmd prompt. Start–>Run then type cmd and click ok. OR Program Files–>Accessories–>Command Prompt.

    what possible reason do you windows users have for a utility like that, those file are mac files they only work with a mac so go play with your .iso’s and .rar’s pc users

  3. jimmy says

    hey genius has it ever occurred to you that we are also mac users with a windows partition or maybe we got the file from a friend and it happens to be a movie and we’d like to watch it on our pc, whatever the case maybe idiotic comments like yours aren’t helpful for anyone, so without further ado go f*** yourself, from a BlackBook owner :)/PC owner

I think mine came with a read me file that explains it pretty well but like i said i dont use or even have the program anymore
