如何在单个 Inno Setup 安装程序中添加 x86 和 x64 VC++ 2019 Redistributables？

Question

我正在尝试在单个设置中添加可重新分发的两种架构 [x32 和 x64] VC++ 2019 (v14.26.28720.03)。我编译成功，但在运行时出现异常ExtractTemporaryFile('#VcInstall');

;Version: v14.26.28720.03
[Setup]
#if arch == "x32"
  #define VcInstall "VC_redist.x86.exe"
#else
  #define VcInstall "VC_redist.x64.exe"
#endif

[Files]
Source: ".\Redist\{#VcInstall}"; DestDir: {tmp}; Flags: dontcopy

[Run]
Filename: "{tmp}\{#VcInstall}"; Parameters: "/q /norestart"; \
    Check: VC2019RedistNeedsInstall; Flags: waituntilterminated; \
    StatusMsg: "Installing VC++ 2019 redistributables..." 

;Version: v14.26.28720.03
[Setup]
#if arch == "x32"
  #define VcInstall "VC_redist.x86.exe"
#else
  #define VcInstall "VC_redist.x64.exe"
#endif

[Files]
Source: ".\Redist\{#VcInstall}"; DestDir: {tmp}; Flags: dontcopy

[Run]
Filename: "{tmp}\{#VcInstall}"; Parameters: "/q /norestart"; \
    Check: VC2019RedistNeedsInstall; Flags: waituntilterminated; \
    StatusMsg: "Installing VC++ 2019 redistributables..." 

我在运行时遇到异常ExtractTemporaryFile('#VcInstall');

内部错误：未找到#VcInstall

我的解决方案基于@Martin的回答：

[Code]
function VC2019RedistNeedsInstall: Boolean;
var 
  Version: String;
begin
  if (RegQueryStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\VisualStudio\14.0\VC\Runtimes\x64', 'Version', Version)) then
  begin
    Log('VC Redist Version check : found ' + Version);
    Result := (CompareStr(Version, 'v14.26.28720.03')<0);
  end
    else 
  begin
    Result := True;
  end;
  if (Result) then
  begin
    ExtractTemporaryFile('#VcInstall');
  end;
end;

您的VcInstall代码是预处理器代码。它在编译时执行，因此会考虑您的开发机器架构。你不想要什么。

相反，使用Is64BitInstallModeor IsWin64（阅读他们的文档以根据您的需要选择正确的）。并且您需要无条件地将两个版本的可再发行版本包含到您的安装程序中。

Source: ".\Redist\VC_redist.x86.exe"; DestDir: {tmp}
Source: ".\Redist\VC_redist.x64.exe"; DestDir: {tmp}

[Run]
Filename: "{tmp}\VC_redist.x86.exe"; Parameters: "/q /norestart"; \
    Check: Is64BitInstallMode and VC2019RedistNeedsInstall('x86'); \
    Flags: waituntilterminated; \
    StatusMsg: "Installing VC++ 2019 redistributables..."
Filename: "{tmp}\VC_redist.x64.exe"; Parameters: "/q /norestart"; \
    Check: (not Is64BitInstallMode) and VC2019RedistNeedsInstall('x64'); \
    Flags: waituntilterminated; \
    StatusMsg: "Installing VC++ 2019 redistributables..."
