Now I think that is odd, to say the least. Their rationale was that they had old programs they needed to run. I politely as I could told them that is what WOW64 and XP mode were for. No answer yet. That's cool. But anyway, has anyone ever done that.......sucessfully?? The fact that they were able to install it suggest that it is possible. BTW, I know that they are running 32bit from a crash dump. Then I looked up the processor type. Strange or what?
