C# windows application Event: CLR20r3 on application start

Question

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:     Problem Event Name: CLR20r3     Problem Signature 01:   logfileviewer.exe     Problem Signature 02:   1.0.0.0     Problem Signature 03:   4f356c9c     Problem Signature 04:   LogFileViewer     Problem Signature 05:   1.0.0.0     Problem Signature 06:   4f356c9c     Problem Signature 07:   94     Problem Signature 08:   44     Problem Signature 09:   System.IO.FileNotFoundException     OS Version: 6.1.7601.2.1.0.256.1     Locale ID:  1033     Additional Information 1:   0a9e     Additional Information 2:   0a9e372d3b4ad19135b953a78882e789     Additional Information 3:   0a9e     Additional Information 4:   0a9e372d3b4ad19135b953a78882e789 

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

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.
