操作系统架构检测脚本答案

【问题标题】：OS architecture detection script操作系统架构检测脚本

【问题描述】：

我刚刚下载了 7zip（x86 和 x64）的两个 .msi 安装程序。有没有人有一个简单的脚本可以用来检测操作系统架构并启动适当的 .msi 文件？

这可能会有所帮助

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
 & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colProcessors = objWMIService.ExecQuery _
  ("Select * From Win32_Processor")

For Each objProcessor in colProcessors
  If objProcessor.Architecture = 0 Then
    Wscript.Echo "This is an x86 computer."
  ElseIf objProcessor.Architecture = 1 Then
    Wscript.Echo "This is a MIPS computer."
  ElseIf objProcessor.Architecture = 2 Then
    Wscript.Echo "This is an Alpha computer."
  ElseIf objProcessor.Architecture = 3 Then
    Wscript.Echo "This is a PowerPC computer."
  ElseIf objProcessor.Architecture = 5 Then
    Wscript.Echo "This is a ARM computer."
  ElseIf objProcessor.Architecture = 6 Then
    Wscript.Echo "This is an ia64 computer."
  ElseIf objProcessor.Architecture = 9 Then
    Wscript.Echo "This is an x64 computer."
  Else
    Wscript.Echo "The computer type could not be determined."
  End If
Next

我发现了一个很棒的 vbscript，由 Monimoy Sanyal 编写，发布在 Microsoft Technet 上。如果 32 位系统在 64 位硬件上运行，它还提供有关系统架构的信息。 https://gallery.technet.microsoft.com/scriptcenter/Determine-If-Your-System-969670e3

你说的很简单，但没有指定语言...

批处理 (.cmd)：

IF /I %PROCESSOR_ARCHITECTURE% EQU x86 (
    msiexec /qn /i 7zip_x86.msi
) ELSE (
    msiexec /qn /i 7zip_x64.msi
)

VBScript (.vbs)：

Set oShell = WScript.CreateObject("WScript.Shell")
proc_arch = oShell.ExpandEnvironmentStrings("%PROCESSOR_ARCHITECTURE%")

If proc_arch = 'x86' Then
    oShell.Run("msiexec /qn /i 7zip_x86.msi"), 0, true 
Else
    oShell.Run("msiexec /qn /i 7zip_x64.msi"), 0, true
End If

PowerShell (.ps1)：

if ($env:PROCESSOR_ARCHITECTURE -eq "x86") {
    & msiexec /qn /i 7zip_x86.msi
} else {
    & msiexec /qn /i 7zip_x64.msi
}
# or ...
if ([Environment]::Is64BitOperatingSystem) {
    & msiexec /qn /i 7zip_x86.msi
} else {
    & msiexec /qn /i 7zip_x64.msi
}

可能很粗糙而且不是很……“安全”……

只需检查 C:\Program Files (x86) 是否存在，它只存在于 64 位系统上。
