如何为Microsoft Store上架的InnoSetup安装程序设置错误返回码

我想用Inno Setup打包exe程序并上架Microsoft Store。在Microsoft Store后台注册应用时，需要为exe程序注册「错误返回码」，可选类型如下：

• 用户取消安装
• 应用已存在
• 安装已在进行中
• 磁盘空间不足
• 需要重启
• 网络故障
• 安装时包被拒绝
• 安装成功

我了解到Inno Setup中用户取消操作可能返回2或5等不同错误码，但Microsoft Store对应仅需注册一个用户取消的条目。这种情况下是否需要自定义Inno Setup的返回码？对应的代码该怎么写？以下是我的原始Inno Setup代码：

#define MyAppName "testApp"

#define MyAppPublisher "My Company, Inc."

#define MyAppExeName "test.exe"

需要自定义Inno Setup的返回码，把多种用户取消场景的返回码统一为一个标准值，同时为其他错误场景匹配Microsoft Store支持的返回码，确保平台能正确识别安装状态。

function InitializeSetup(): Boolean;

  // 预检查应用是否已存在，匹配Microsoft Store的「应用已存在」类型
  if DirExists(ExpandConstant('{app}')) then
  begin
    MsgBox('应用已存在！', mbError, MB_OK);
    ExitCode := 1603; // 对应「应用已存在」的标准返回码
    Result := False;
  end;
end;

procedure DeinitializeSetup();
begin
  // 统一Inno默认的用户取消返回码（2、5）为Microsoft Store识别的1602
  if (ExitCode = 2) or (ExitCode = 5) then
  begin
    ExitCode := 1602; // 对应「用户取消安装」的标准返回码
  end;
end;

// 捕获安装过程中的取消操作
procedure CurStepChanged(CurStep: TSetupStep);
begin
  if CurStep = ssInstall then
  begin
    if WizardForm.CancelButton.Enabled then
    begin
      ExitCode := 1602;
    end;
  end;
end;

关键说明 #

1. 标准返回码映射：使用Microsoft Store兼容的标准返回码：
   • 0：安装成功
   • 1602：用户取消安装
   • 1603：应用已存在
   • 1607：磁盘空间不足
   • 3010：需要重启
2. ExitCodeList配置：在[Setup]段声明允许使用的退出码，防止Inno Setup覆盖自定义值。
3. 统一取消场景：通过DeinitializeSetup将Inno默认的用户取消返回码（2、5）替换为1602，确保Microsoft Store能统一识别该场景。
