请允许我将您引导至 使用 Visual C++ 进行 64 位编程.特别是子页面 如何:配置面向 64 位平台的 Visual C++ 项目 包括针对 Express 版的此注释:

Allow me to direct you to 64-Bit Programming with Visual C++. In particular, the sub-page How to: Configure Visual C++ Projects to Target 64-Bit Platforms includes this note for the Express Edition:

默认情况下，64 位工具在 Visual C++ Express 上不可用.要在 Visual C++ Express 上启用 64 位工具，请安装 Windows 软件开发工具包 (SDK) 以及 Visual C++ Express.

64-bit tools are not available on Visual C++ Express by default. To enable 64-bit tools on Visual C++ Express, install the Windows Software Development Kit (SDK) in addition to Visual C++ Express.
