Although most x86 processors used in new personal computers and servers have 64-bit capabilities, to avoid compatibility problems with older computers or systems, the terms x86-64 and 圆4 are often used to denote 64-bit software, with the term x86 implying only 32-bit.' MS will hopefully be concentrating on developing the software at this stage, instead of idiot-proofing their documentation. This may sometimes be emphasized as x86-32 to distinguish it either from the original 16-bit x86-16 or from the newer 64-bit x86-64 (also called 圆4). If you had googled 'x86' the first entry is a wikipedia entry discussing exactly this, and here's the second paragraph: 'As the x86 term became common after the introduction of the 80386, it usually implies a binary compatibility with the 32-bit instruction set of the 80386. Alternatively, if common sense and deduction are not your strongest suits, try google. It's a duff convention as the 806 were 16 bit, while the 80386, 80486 and Pentium (80586) were 32 bit, but the point is that 32 bit windows runs on current, recent and not-so-recent x86 microprocessors. x86 refers to the product family of the 32 bit microprocessors used to run 32 bit windows. If you'd intuited that the 圆4.exe version is indeed the 64 bit one, then you could deduce that the x86.exe version is for 32 bit systems. This is free, unsupported software - by what right are you up on your high horse? As it's free and unsupported, if you're lacking a bit of knowledge, then a little common sense and deduction will help. As you know, it doesn't tell you in the article. No-one answered because you asked a rhetorical question.
