Question

我们最近将.NET应用程序（包含infragistics控件的C＃，Visual Studio 2010，Click Once部署）从.NET 2.0运行时更新到.NET 4.0运行时。为此，我们将所有项目属性从2.0更新为4.0，因此不是客户端配置文件。我们还将相应的先决条件从2.0更改为4.0。现在，我们在向客户推出应用程序时遇到了一些问题。

我们有两种安装应用程序的方法： 1）使用部署服务器的URL：这里没问题。 2）使用当前的应用程序快捷方式 - 大多数用户都这样做。这个选项给出了问题。

在首次安装运行期间，安装失败。以下是clickonce日志的摘录。奇怪的是平台版本信息中有2.0个引用，但是，.NET 4.0运行时已在安装点预先安装。不知道这是否与问题有关。第二个奇怪的是错误：“从文件Progress.Messages.dll加载清单时发生异常：清单可能无效或文件无法打开。”也许并不重要，但这个DLL已签名。
