I ran through this, and did the download on an XP computer. What I ended up with was the 32-bit version (quad-core 64-bit CPU, 8G memory) and no ISO and no option to create an ISO. There was NO option to choose 32 or 64 bit either. This was all kept very hidden by Microsoft with no indication until it was all too late.
I have since found that lots of other people have been caught by this same trap. AND, there are no genuine ISOs anywhere available for download. Microsoft have stuffed this one up badly.
