我想通过Windows Forms部署一个ClickOnce项目。我已将其设置为在启动之前检查更新，没有安装的先决条件，也不需要修改安全设置。我将应用程序设置为脱机可用性。
我设置了IIS并发布了该应用程序。这成功了。
我使用ClickOnce将应用程序安装到承载应用程序文件的开发服务器上。这很好用于安装。它提出了关于不验证我点击的发布者信息的安全警告，然后我的应用程序出现了。
我从远程计算机浏览到ClickOnce应用程序的安装程序页面，然后单击“安装”按钮。弹出对话框窗口，显示“验证要求”，然后弹出错误，显示“无法继续此应用程序格式不正确”并提供详细信息（见下文）。当我在服务器本地安装时，我从未收到安全警告。
对我来说，奇怪的是，如果我选择应用程序在线以及离线，ClickOnce安装将会起作用并且应用程序将启动。为什么这不起作用？部署非常简单，只有EXE文件和exe.config文件。没有DLL文件或类似的东西。
我现在已经创建了一个干净的新项目并添加了所有内容，并通过ClickOnce部署获得了相同的结果。我不知道这是配置问题还是安全/访问问题。
我可以使用ClickOnce安装到托管文件的网络服务器。但是任何其他机器都无法安装。
我还设置了一个新用户帐户“clickonceuser”，并让他们完全控制Web服务器的目录。我将IIS设置为“clickonceuser”并点击测试按钮，验证用户和文件系统访问权限。
