Current Release version 6.12.2.633 – February 26, 2010

The Debugging Tools for Windows 64-bit version is now available as a standalone component from the Windows Software Development Kit (Windows SDK). Debugging Tools for Windows includes WinDbg, a powerful debugger with a graphical interface and a console interface, as well as the console-based debuggers NTSD, CDB, and KD.

Download Debugging Tools from the Windows SDK

The Debugging Tools are listed in two places on the Installation Options screen in the Windows SDK Setup Wizard:

  • Select the Debugging Tools option under the Common Utilities if you want the x64 version of the Debugging Tools and you are installing on an x64 computer. This option automatically detects the CPU architecture of the computer on which you are installing the tools and it is the fastest method of installing the tools.

  • Select the Debugging Tools option under the Redistributable Packages to download all three versions of the Debugging Tools (x86, x64, Itanium).

After you select the appropriate Debugging Tools option as described above, clear the check boxes for the other options so that you do not install unnecessary items. The Common Utilities option downloads the Debugging Tools into a Debugging Tools for Windows folder under your Program Files folder. The Redistributable Packages option downloads the Debugging Tools to C:\Program Files\Microsoft SDKs\Windows\v7.1\Redist\Debugging Tools for Windows.

You can also install the Debugging tools from the Windows Driver Kit (WDK) ISO image.

System Requirements

The following are system requirements for the 64-bit version of Debugging Tools for Windows:

  • 64-bit versions of Windows 7, Windows Server 2008 R2, Windows Server 2008, Windows Vista, Windows XP, and Windows Server 2003.

  • Approximately 25 MB of hard disk space.

When to Use 64-bit Debugging Tools

The 64-bit versions of Debugging Tools for Windows allow you to debug both 32-bit and 64-bit user-mode applications running on 64-bit processors. Use this package to debug both the application and the WOW64 emulator.

If you are debugging an application on an Intel Itanium or x64 processor, you should use the package designed for the specific processor as listed here. The native 32-bit package is the best choice for all other debugging scenarios.
