如何32位cmd.exe启动64位cmd.exe在Windows 2003 x64？ [英] How can 32-bit cmd.exe launch 64-bit cmd.exe in Windows 2003 x64?

问题描述

后续追踪 Windows2k8 64中的7zip执行权限

我试图避免一个过于复杂的构建过程，使多个7zip exes。我只需要一个.cmd启动我的java进程读取一些64位注册表项后。

上面的问题发现了一个骗子，让win2k8检测一个32位的cmd.exe和交换它到64位，有没有办法在win2k3这样做？有一个Windows修补程序允许reg.exe在32位模式下访问64位条目，但我不能放心，在客户的服务器上，所以解决方法是一个没有去。

c：\Windows \System32 code>文件夹而不重定向到 c：\Windows \SysWow64 文件夹。在Win2008中，您可以通过访问 c：\Windows \Sysnative 路径来实现此目的。不幸的是，在Win2003上需要修补程序（请参阅 http://support.microsoft.com/kb/942589 ）。<有一个解决方法 - 您可以创建一个NTFS连接点，指向 c：\Windows \System32 文件夹并使用到该连接点的路径，而不是 c：\Windows \System32 。使用System Internals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。

Follow up to 7zip execution permissions in Windows2k8 64

I'm trying to avoid having an overly complicated build process to make multiple 7zip exes. I just need a .cmd to kick off my java process after reading some 64-bit registry entries. However, to succeed with a single exe, it needs to be 32 bit.

The above question found a trick for getting win2k8 to detect a 32 bit cmd.exe and swap it to 64 bit, is there a way to do this in win2k3? There's a windows hotfix that allows reg.exe to access 64 bit entries in 32bit mode, but I can't be assured that's on the customer's server so that workaround is a no go.

解决方案

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).

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.
