It can not be done.

At least not easily

CD's like this have copy protection built in, and it isn't as simple as making a rip of the .ISO.

There are some threads about it on the Internet.

But of course, I'll add the usual DMCA/copyright disclaimer. You'll need to install all kinds of copy protection bypass applications, and even then it might not work. I understand the frustration, especially since you are a legitimate owner of the software, but companies like Rosetta Stone have to deal with so much theft of their stuff that they have no other choice.
