Installing Spanish version of norton 360

I have a three computer membership for norton 360. My fiance speaks mostly spanish and here windows 7 laptop is spanish. I want to know if I can install the spanish version of norton 360 and use one of my two remaining keys to activate. The problem is installing it on her laptop because I do not read much spanish. If it is possible to do this, is there a way for her to receive instructions in spanish on how to install. Thank you very much for your time. David
