在另一台计算机上运行C#程序时出现System.IO.FileLoadException

该项目是一个.Net 4项目,在我的开发机器上没有问题.我创建了一个MSI安装程序包,当我添加可执行文件Visual Studio时,计算出依赖关系,并在EXE中添加所需的DLL.

当我在我的开发机器上运行安装程序时,一切正常.但是,当我将安装程序复制到安装了.Net Framework 3.5和.Net Framework 4的空白虚拟机时,安装程??序说所有内容都已成功安装,当我查看程序文件文件夹时,所有的DLL也都存在,但是当我尝试运行软件未加载的软件,并在事件查看器中显示.Net Runtime错误.

错误如下

错误消息并没有真正帮助我弄清楚什么是错误的,因此在应用程序启动事件中我添加了try catch语句但是异常永远不会被捕获.我还在第一个应该加载的对话窗口上执行的InitialiseComponent()方法中添加了try catch,但是从来没有捕获到catch,所以我看不出导致错误的原因.

我怎样才能弄清楚这个问题是什么并修复它？
