下载并运行子安装-IDP进度栏在下载过程中不会移动

Question

好，所以我创建了以下iss，但是进度条没有移动。我希望安装文件下载并运行其他安装程序。一切正常，但进度条不动。

有什么想法吗？其他一切都很好。

=======编辑========

我有一个解决方法，将显示详细信息部分。无论如何，这可能更合适。仍然不确定为什么总进度没有更新。

 #define MyAppName "My Program Setup Downloader"
 #define MySetupAppName "My Program Setup.exe"
 #define MySetupUrlFolder "https://www.example.com/folder/"
 #pragma include __INCLUDE__ + ";" + "c:\Program Files (x86)\Inno Download Plugin\"

 [Setup]

 AppName={#MyAppName}
 AppVerName={#MyAppName}
 DisableReadyPage=yes
 DisableFinishedPage=yes
 CreateAppDir=no
 Uninstallable=no

 #include <idp.iss>

 [Code]

 var FileName: string;

 procedure InitializeWizard;
 var DownloadUrl: String;
 begin
   FileName := ExpandConstant('{tmp}\{#MySetupAppName}');
   DownloadUrl := '{#MySetupUrlFolder}{#MySetupAppName}';
   idpAddFile(DownloadUrl, FileName);
   idpDownloadAfter(wpSelectDir);
 end;

 function NextButtonClick(CurPageID: Integer) : boolean;
 var ResultCode: Integer;
 begin
   if CurPageID = IDPForm.Page.ID then
   begin
     Result := Exec(FileName, '', '', SW_SHOW, ewWaitUntilTerminated, ResultCode);
     if not Result then MsgBox('Error Running Downloaded Setup File', mbError, MB_OK);  
     Result := True;       
   end
     else Result := True;
 end;

我确实得到了相同的行为。我不明白为什么。

但是，由于只有一个文件，可以用文件进度条替换总进度条：

procedure CurPageChanged(CurPageID: Integer);
begin
  if CurPageID = IDPForm.Page.ID then
  begin
    IDPForm.TotalProgressBar.Visible := False;
    IDPForm.FileProgressBar.Top := IDPForm.TotalProgressBar.Top;
    IDPForm.FileProgressBar.Visible := True;
    IDPForm.DetailsButton.Visible := False;

    IDPForm.DetailsVisible := True;
  end;
end;
