如果安装了程序，Inno Setup会跳转到第二页

Question

首次安装时，一切运行顺畅，但是如果我再次运行安装程序，它只会跳到第二页询问我想要放置其他文件的位置，然后在就绪页面中只显示其他文件文件夹的参数。设置了忽略版本标志，还有什么呢？

  // Set default folder if empty
  if DataDirPage.Values[0] = '' then

  S := S + MemoDirInfo + NewLine + NewLine;

  S := S + '32bit VSTi' + NewLine;
  S := S + Space + DataDirPage.Values[0] + NewLine;

  Result := S;
end;

function GetDataDir(Param: String): String;
begin
  { Return the selected DataDir }
  Result := DataDirPage.Values[0];
end;

如果查看here，您会看到DisableProgramGroupPage的默认值为auto。如上所述：

  

如果设置为auto，则启动时安装程序将在注册表中查找   看看是否已经安装了相同的应用程序，如果已安装，它会   不显示选择开始菜单文件夹向导页面。

如果您查看帮助文件中的其他Disable条目，您会看到它们的行为相同。在新安装期间仅显示这些页面是合乎逻辑的。通过将这些行为设置为no来更改默认行为。
