要从32位cmd.exe启动64位cmd.exe，您必须能够访问 c：\Windows\ System32 文件夹，而不会重定向到 c：\Windows\SysWow64 文件夹。在Win2008中，您可以通过访问 c：\Windows\Sysnative 路径来实现。不幸的是，在Win2003上需要一个修补程序（请参见 http://support.microsoft.com/kb/942589 ）。

To launch 64-bit cmd.exe from 32-bit cmd.exe you must be able to access c:\Windows\System32 folder without being redirected to c:\Windows\SysWow64 folder. In Win2008 you can achieve this by accessing c:\Windows\Sysnative path. Unfortunately on Win2003 a hotfix is required (see http://support.microsoft.com/kb/942589).

有一种解决方法-您可以创建一个NTFS交接点，该交接点直接指向 c：\Windows\System32 文件夹并使用到该交接点的路径，而不是 c：\Windows\System32 。使用系统内部的 junction.exe ，我设法从32位cmd.exe创建了这样的连接点并启动64位cmd.exe。

There is a workaround - you can create an NTFS junction point that directs to c:\Windows\System32 folder and use path to that junction point instead of c:\Windows\System32. Using System Internals' junction.exe I managed to create such a junction point from 32-bit cmd.exe and launch 64-bit cmd.exe.
