Good Evening, my name is Nisse and I am new to MATLAB Central, nevertheless I hope to find answers for my problems here. :)

I created an .net/c# WindowsForm-application with VS 2010. I am using MATLAB 2009b 64-Bit.

My app got following code, that's going to be executed on button_press:

MLApp.MLAppClass matlab = new MLApp.MLAppClass();

                matlab.Execute("a = [ 1 2 3 ; 4 5 6 ; 7 8 9];");
                matlab.Execute("plot(a);");

This whole thing is working perfectly fine, I am glad that this is so easy.
BUT NOW: the problem!
I sent this programm as an exe to my friend who uses MATLAB 2008a 32-Bit and when he executes the app, an error occurs.
So we tried it other way round: He wrote also the application with VS2010, just copied my code, compiled it and it worked fine!
Then he sent it to me, I tried: same error as he got when executing my file.
Could you tell me where the problem is? I am pretty sure it has to do with the different MATLAB versions.

Thanks for your help in advance,

your Nisse!

For better "debugging" I copy the error code that I got from his application to my thread: (the first part under "exception text" looks like the most important!)

"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."

Hi dear:
I read your problem in the internet:
1. http://www.mathworks.com/matlabcentral/newsreader/view_thread/294857
2. http://compgroups.net/comp.soft-sys.matlab/Problem-using-COM-automation-server-out-of-net-Application
3. http://mathforum.org/kb/thread.jspa?messageID=7249825&tstart=0

I have a same problem, but can't solve it.
i develop a C# program by Matlab, but not running to another windows. because matlab didn't install on the another windows?

are you can find any solution?
Please help me and share your solution with me, if you find it.
Tanks,

Best regards.
A.Goodarzi
