Call it a KB article. I have put up with running Vista 32 on my 64 bit machine for two years because of the lousy installation design. Even the KB article Installation choices for 64-bit consumer versions of Windows Vista makes it tough to understand the one clear set of instructions that are eventually listed under the heading Installing a 64-bit version of Windows Vista on a computer that is running a 32-bit version of Windows XP or of Windows 2000.
