I created a C# application and installed it on my test box. My app works perfect on my dev box, but when I install in on a different machine it crashes in the Main(). I get the EventType: CLR20r3

here is the Event Message

    Problem signature:

I used the details and looked up the error code in IL Disassembler and cam back with the following...

    Method #5 (06000094) 
    -------------------------------------------------------
    MethodName: .ctor (06000094)
    Flags : [Public] [HideBySig] [ReuseSlot] [SpecialName] [RTSpecialName] [.ctor] (00001886)
    RVA : 0x000081d0
    ImplFlags : [IL] [Managed] (00000000)
    CallCnvntn: [DEFAULT]
    hasThis 
    ReturnType: Void
    No arguments.

.NET 4.0 has been uninstalled and re installed on the system and did not change anything. I have searched all over the net and everyone with the same problem do not seem to have a solution. I have now spent a day and a half on this problem. I would hate to miss my deadline do to not being able to launch the application.

This is the only code in my Main()

    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new frmMain());
    }

Here are the details from the Event Viewer

    Application: LogFileViewer.exe
    Framework Version: v4.0.30319
    Description: The process was terminated due to an unhandled exception.
    Exception Info: System.IO.FileNotFoundException
    Stack:
        at LogFileViewer.frmMain.InitializeComponent()
        at LogFileViewer.frmMain..ctor()
        at LogFileViewer.Program.Main()

EventData

    Application: LogFileViewer.exe 
    Framework Version: v4.0.30319 
    Description: The process was terminated due to an unhandled exception. 
    Exception Info: System.IO.FileNotFoundException 
    Stack: at LogFileViewer.frmMain.InitializeComponent() at LogFileViewer.frmMain..ctor() at LogFileViewer.Program.Main() 

Not sure how the designer can have a FileNotFound Exception. I am using the DotNetBar.dll and I am referencing it out of the install directory, so that should be good. I can post my designer if you want, but there is quite a bit there.

I've seen this same problem when my application depended on a referenced assembly that was not present on the deployment machine. I'm not sure what you mean by "referencing DotNetBar out of the install directory" - make sure it's set to CopyLocal=true in your project, or exists at the same full path on both your development and production machine.
