#NSIS #判断系统版本

本文介绍如何利用NSIS脚本判断安装程序运行时的系统版本，区分是X64还是X86架构。

            ${ElseIf} $R1 == 1
                    MessageBox MB_OK "Windows XP SP $R3"
            ${ElseIf} $R1 == 2

            ${EndIf}
    ${EndIf}
    ; version
    MessageBox MB_OK "Kernel $R0.$R1 build $R2"
FunctionEnd

下面一段用来判断X64还是X86系统：

Function "IS64"
; x86 or x64:
    System::Call "kernel32::GetCurrentProcess() i .s"
    System::Call "kernel32::IsWow64Process(i s, *i .r0)"
    StrCmp $0 "0" is32bit is64bit
    is32bit:
			StrCpy $R5 "x86"
            ;MessageBox MB_OK  "32 bit"
            Goto exit
    is64bit:
		StrCpy $R5 "x64"
            ;MessageBox MB_OK  "64 bit"
    exit:
FunctionEnd
