I know. I didn't say or imply that there were. What I'm saying is that in the boxed retail version you get the discs for 64 and 32 bit and one key that you can use for either one as you choose but not both at the same time. The Feedback program gives you two discs (one 64 and one 32) but each with its own unique key. So you effectively have two separate copies of Windows that you can use at the same time.
