我有一个非常有趣的问题。我已经浏览过“＃无法下载应用程序＆＃34;而且我没有看到任何特定于iPhone版本的内容。我有一个内部应用程序已经分发并正在所有的iPhone5上工作。但是，当我尝试将其安装到iPhone4s上时，我得到了＃34;无法下载应用程序＆＃34;错误。这告诉我它不是分发文件（.ipa或配置文件）问题，而是其他什么？我在尝试下载应用程序时搜索了控制台，但我没有看到任何错误。我希望有人能在这里看到我不喜欢的东西！
以下是尝试安装应用程序时失败的iPhone4S和iOS 7.1.2的控制台日志：

此时我会尝试任何事情。我只是不明白有什么不同。我正在使用完全相同的URL，它被定向到相同的d / l，即使控制台日志几乎完全相同，直到iPhone4s出错。
有人有什么想法吗？
答案 0 :(得分：0)
看起来大约一年前他们手机上仍然有一个旧的配置文件（它将在3天后到期），所以我让他们删除它并重试安装并且它有效！
