call was rejected by callee

My application was working fine on my win 7 64 bit machine.

I tried to run the winforms visual studio 2008 .NET C# application on a different win 7 64 bit machine and now I am getting this error:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

here's a screenshot:

I was wondering if anyone else has had this issue?

what does the error mean?

Here is a quick and dirty solution, add a thread.sleep after you create the excel object.

Something like this:

var app = new Microsoft.Office.Interop.Excel();
Thread.Sleep(2000);
