根据https://status.github.com/messages https://status.github.com/messages，目前服务器没有问题。 我使用的是个人计算机，因此连接应该不会有任何问题。我尝试直接从下载应用程序http://github-windows.s3.amazonaws.com/GitHub.application http://github-windows.s3.amazonaws.com/GitHub.application，但结果是一样的。

我运行的是 Windows 8.1 Pro x64。

编辑 1：目前，我正在解决无法安装 GitHub for Windows 的问题，方法是首先将其安装在另一个系统上，然后从 %appdata%\Local\Apps\2.0 中获取新安装的文件，并将它们移至具有该功能的系统安装时遇到麻烦。 （完整目录为 %appdata%\Local\Apps\2.0\EWG9HYRR.BKG\2XKOJCRD.XRD\gith..tion_317444273a93ac29_0002.0002_f44dcb2e9d4cde94）。

此解决方法的主要警告之一是，在有问题的系统上，Windows 版 GitHub 将报告“这不是网络部署的应用程序”。因此不会自动更新。

联系支持人员后，他们给我发了电子邮件，帮助我解决了 GitHub for windows 无法安装的问题。

这是 ClickOnce 应用程序缓存的问题。

1. 在继续之前，请确保您已连接。
2. 有时防火墙可能会阻止此操作*。应用
3. 所以关闭你的防火墙private and public配置文件，然后重试。
4. 如果问题仍然存在，您可以使用下面指定的流程。

1. 按住Windows键和类型R.
2. Type in rundll32 %SystemRoot%\system32\dfshim.dll CleanOnlineAppCache在运行对话框中并点击Enter.

然后尝试安装该应用程序。

如果这不起作用，有一种更手动的方法来确保清除缓存 - 您可以直接删除 ClickOnce 应用程序文件夹。在Windows Vista或更高，这将是%LocalAppData%\Apps\2.0目录。只需删除%LocalAppData%\Apps\2.0目录并重新启动 github for windows。

如果运行安装程序后似乎没有任何反应，您可能需要重新启动 Windows，或者explorer.exe（如果使用 .msi 安装程序，该应用程序可能位于：%LocalAppData%\GitHubDesktop)
