As per the CD sleeve I got it in:
PhotoDeluxe Serial # HJW300B71000-621
the "300B" section, I'm *assuming* is "three hundred B" but either might be letter Os as well, so try that if this doesn't work.

Also, regarding the ISO, since it's supposed to be a multi-format deal for Mac/Win I don't know how well MagicISO exported the Mac fork, if at all, into the ISO. If you can test it on a Mac, let me know, but I probably won't do anything about it if it doesn't work.
