前言

使用Inno Setup打包Windows桌面程序，有时候可能需要根据系统版本不同来处理对应的流程， 比如安装不同的驱动，或者执行不同的脚本等等，本文主要阐述如何在打包脚本中添加函数去判断不同的系统版本。

直接上代码：

//Func: Get Windows Version
function MyGetWindowsVersion:String;  
varosInfo: RTL_OSVERSIONINFOW;
beginosInfo.dwOSVersionInfoSize := SizeOf(osInfo);RtlGetVersion(osInfo);//test//MsgBox(Format('Get windows Version : Major %d,Minor %d,Build %d', [osInfo.dwMajorVersion, osInfo.dwMinorVersion, osInfo.dwBuildNumber]), mbInformation, MB_OK);//windows11 Windows 11的主版本号是10，次版本号是0，内部版本号大于等于22000if(osInfo.dwMajorVersion = 10) and (osInfo.dwMinorVersion = 0) and (osInfo.dwBuildNumber >= 22000) thenbeginResult:='WIN11';Exit;end;//windows10if(osInfo.dwMajorVersion = 10) and (osInfo.dwMinorVersion = 0) thenbeginResult:='WIN10';Exit;end;//windows8.1if(osInfo.dwMajorVersion = 6) and (osInfo.dwMinorVersion = 3) thenbeginResult:='WIN81';Exit;end;//windows8if(osInfo.dwMajorVersion = 6) and (osInfo.dwMinorVersion = 2) thenbeginResult:='WIN8';Exit;end;//Windows 7if(osInfo.dwMajorVersion = 6) and (osInfo.dwMinorVersion = 1) thenbeginResult:='WIN7';Exit;end;//Windows XPif(osInfo.dwMajorVersion = 5) and (osInfo.dwMinorVersion = 10) thenbeginResult:='WINXP';Exit;end;//其它Result:='OTHER';
end;function MySystemIs(WinVers: String): Boolean;
begin
Result := (MyGetWindowsVersion = Uppercase(WinVers));
end;

调用也很简单，比如需要在执行安装过程中判断系统来安装某个附加程序：

[Run]
Filename: "{app}\{#VCName}"; Parameters: "/S"; StatusMsg: "Installing VC++ redistributables..."; Check: MySystemIs('WIN11');

通过调用 MySystemIs传入系统版本名称，即可判断当前是否为想要的系统了。
