Microsoft have a program for registering a product and then allowing the use of "Designed for Windows XP" logo by that product vendor.
It seems that this is also open to products that run on Windows XP 64, but that there is no distinct logo for 64-bit.
A product designed for Windows XP 64 or Windows 2003 64, may in fact be unable to run on 32-bit versions, so surely a seperate logo and designation exists
So, is there in fact a logo: "Designed for Windows XP 64" or not
Thanks
