我在安装 ClickOnce vb.net windows 窗体应用程序时遇到问题。我尝试了几个在此站点上建议的解决方案，但没有一个有帮助。

我的应用程序是用 VS2010(.NET 4.0 Framework)构建的，并部署到我的开发机器上的本地文件夹 C:\inetpub\wwwroot\AppName 但我已将以下地址指定为安装地址 https://localhost/AppName/

当我在 IE 中点击“运行”按钮时出现以下错误。 “如果在安全模式与非安全模式之间切换时发出警告”在 IE 中未选中。 对此的任何帮助将不胜感激。完整的错误消息如下所示。

Launching Application.
URLDownloadToCacheFile failed with HRESULT '-2146697210'
Error: An error occurred trying to download 'http://MachineName:90/publish.htm/AssemblyName.application'

最佳答案

在我们的系统上，当运行 setup.exe 时，如果 deploymentProvider 中的代码库 URL 设置为 http，则它可以工作，但 https 失败并显示 URLDownloadToCacheFile failed with HRESULT '-2146697208'。但是，将下载 ourapp.application 文件。

原来是 SSL 缓存被禁用，以下注册表更改解决了这个问题。

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"DisableCachingOfSSLPages"=dword:00000000
