如何从 Wow64 下运行的 vb 脚本启动以 64 位模式运行的 Vb 脚本

Question

我有一个 VB 脚本被迫在 Wow64 模式下运行。我想让它以本机 64 位模式启动另一个脚本或自身。有办法做到这一点吗？

初始脚本是通过显式调用 cscript.exe 来调用的（不确定这是否有影响）

谢谢

Answer 1

显然它非常简单。

在 Windows Vista 及更高版本中，C:\Windows\Sysnative 中有一个别名文件夹。如果您调用它，它不会重定向到 c:\windows\SysWow64 32 位文件夹，但会强制调用本机 64 位可执行文件

因此，您可以运行通过调用 %windir%\Sysnative\cscript.exe，然后提供脚本名称作为参数，从以 wow64 模式运行的 vbscript 获取 64 位模式的 vbscript。

但是，这仅适用于 Windows Vista 或更高版本。有一个修补程序可以在 Windows XP/2003 中启用此 Sysnative 文件夹

将以下代码放在脚本顶部以检测操作系统是否为 64 位，然后以 32 位模式重新运行

' ***************
' *** 64bit check
' ***************
' check to see if we are on 64bit OS -> re-run this script with 32bit cscript
Function RestartWithCScript32(extraargs)
Dim strCMD, iCount
strCMD = r32wShell.ExpandEnvironmentStrings("%SYSTEMROOT%") & "\SysWOW64\cscript.exe"
If NOT r32fso.FileExists(strCMD) Then strCMD = "cscript.exe" ' This probably won't work if we can't find the SysWOW64 Version
strCMD = strCMD & Chr(32) & Wscript.ScriptFullName & Chr(32)
If Wscript.Arguments.Count > 0 Then
 For iCount = 0 To WScript.Arguments.Count - 1
  if Instr(Wscript.Arguments(iCount), " ") = 0 Then ' add unspaced args
   strCMD = strCMD & " " & Wscript.Arguments(iCount) & " "
  Else
   If Instr("/-\", Left(Wscript.Arguments(iCount), 1)) > 0 Then ' quote spaced args
    If InStr(WScript.Arguments(iCount),"=") > 0 Then
     strCMD = strCMD & " " & Left(Wscript.Arguments(iCount), Instr(Wscript.Arguments(iCount), "=") ) & """" & Mid(Wscript.Arguments(iCount), Instr(Wscript.Arguments(iCount), "=") + 1) & """ "
    ElseIf Instr(WScript.Arguments(iCount),":") > 0 Then
     strCMD = strCMD & " " & Left(Wscript.Arguments(iCount), Instr(Wscript.Arguments(iCount), ":") ) & """" & Mid(Wscript.Arguments(iCount), Instr(Wscript.Arguments(iCount), ":") + 1) & """ "
    Else
     strCMD = strCMD & " """ & Wscript.Arguments(iCount) & """ "
    End If
   Else
    strCMD = strCMD & " """ & Wscript.Arguments(iCount) & """ "
   End If
  End If
 Next
End If
r32wShell.Run strCMD & " " & extraargs, 0, False
End Function
