It is the CD version. Be aware, however, that it does not work with Windows XP (regardless of what the box states) and there is very little help available. All I got from the RS tech support was, "You should return it." I had to return mine. I was very much looking forward to using it. I did everything I could to get it to work.
yes, the box version has a CD-ROM which loads onto your computer. I have used the computer version on my PC a few times and there's little difference from the internet version other than appearance. However, you will not be able to chat online with other learners, or play games online with other learners. You can still play games on the computer version.
My version SEEMS to suggest that I can load up to five learners on one version, but I haven't tried. Thus a learner would logon and the program would take the learner to where he/she left off. Each learner can proceed at their own pace (I think.) Four or five learners might replace the online chat feature.
I am very disappointed with the product. The installation instructions did not apply to Amazon purchases and I had to obtain Rosetta support to even install. The immersion process leaves a lot to be desired. I spent a lot of time trying to figure out which question would apply to which illustration. I would not recommend this product to anyone.
That's a tough question. It depends on how many years ago you lived in Latin America, how well you "got by" and how much you still remember. Level 1 is primarily pronunciation (which you probably don't need), vocabulary (which you might not need) and conjugation of regular verbs.
