I bought adobe CS6 design standard (CD) last year in the month of july and didn't active my product yet. I bought in from the University of Washington, Seattle store on a student and teacher licensing. I have the product code with me. I am a Mac user and I don't have cd drive in my computer and I am indeed to get this product activated now. How can I install this without cd drive?  Anyone please help me with this issue?
