I bought Rhinoceros v.4.0 yesterday at my school. I am currently running Windows Vista on my MacBook Pro with Parallels and the disk won't run when I put it in. First, the auto-run menu doesn't start up when the disk is inserted and then when I go into the actual disk using My Computer and try to run the setup from there, there is a message that comes up that says "The file "y:\setup.ini either does not exist or is not formatted correctly". I called the help service offered through Rhino and followed the instructions that they gave me, and they could not figure out what could be wrong with it.
