Well, there may be two versions for developers. Not everyone has their hands on a 64-bit processor yet. And about only installing it once, I mean through product activation. Like Windows XP, you had originally I believe several liscenses. Then, after you use all them up, you need to buy a new liscense(which is 80$).caipirinha said:there are 2 versions for beta 1 , 32 and 64bit , the name is quite apropriate since they're putting so much emphasis on the visual part of the OS and on viewing things , vista = view
and about installing it only once, hoax.
