I am a college student and I have been using MathCad for quite a while. My old license expired in October, and I am now in a class that requires MathCad 11, so I just purchased a student license for it. I have MathCad 10 on my computer, but not 11. When I went to download the image to get 11, it told me there were no products entitled to software updates. I do not want to activate the license on 10 because I need it to be compatible with 11. How to I download 11 onto my computer so I can activate the license?
