我在服务器上发布并安装了一个Windows 窗体应用程序，但是当我尝试使用它时，很遗憾地给了我这个错误：

************** Exception Text **************
System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {40942A6C-1520-4132-BDF8-BDC1F71F547B} failed due to the following error:

    at System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
    at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

这对我来说似乎是一个“.dll”文件，但我不知道是哪一个，或者这是否是真正的问题。什么可能导致这种情况？我该如何解决？

这是 COM 互操作的问题。您需要手动将 dll 文件复制到应用程序或将 dll 文件打包到安装程序中。
