Hello, My apologies for the newbie question: I'd like to install Mathcad 13 on Windows XP in Parallels (which is set up and has installed other programs) When I insert the Mathcad CD into my MacBook Pro, the computer makes a bit of noise and ejects the CD unread. When I insert the mathcad CD into my PC, it reads it fine and offers to do the install. How can I install mathcad in Parallels if the mac doesn't recognize the CD? Something tells me this is a dumb question with an easy fix, but I'm not having success finding help online. Thanks for any help, Mike
