呃，我讨厌微软错误的行为，就像x86是32位一样。  x86是平台archetecture-64位x86仍然是x86。

Ugh, I hate how Microsoft incorrectly acts like x86 is 32-bit.  x86 is the platform archetecture-64-bit x86 is still x86.

无论如何，无论哪个匹配你的操作系统。 大多数人都有64位Windows。 有几种方法可以区分，但最简单的方法可能是启动，然后开始输入"32位"。然后单击结果"查看您是否拥有
32或64位版本的Windows"。

Anyway, whichever matches your OS.  Most people have 64-bit Windows.  There are several ways to tell the difference, but the easiest is probably to hit start, then start typing "32-bit" and click the result for "see if you have the 32 or 64-bit version of Windows".
