deploying Matlab C++ library to 64 bit

I am currently developing a C++ program to interact with a C++ shared library created with Matlab R2007a compiler. Somehow, I cannot pass the initialization stage. First I call mclInitializeApplication(NULL,0)) and this goes ok. But when I call let's say MyFunctionInitialize() it fails.
Previously this was working but now when I deployed the application on a 64 - bit machine, it does not work anymore. Could the 64 bit environment be a problem?

Hi,
is the target OS of the same type like the OS where the DLL is compiled on? What error do you get?

No, the DLL is compiled on a computer with OS: Windows XP and the taget machine has Windows server 2008 R2

Dont run the dep walker on the shared lib. Compile everything into an EXE and then make a RUNTIME PROFILE of that exe. The right steps for this are:
i) choose File -> open and select your application
ii) choose Profile -> start profiling
iii) a window pops up
iv) press okay
v) your applications should start now
vi) after your application finished running investigate the log for hints what went wrong.
You can also:
vii) choose File -> save as
viii) upload the dwi file somewhere an post the link here

I compiled everything into a console application, deployed it on the target machine and first, it said that MSVCR100D.dll is missing. After placing that into exe directory, the application worked. But.. in my C++ program it is a little bit different because it is all packed into a win32 dll, called by a ASP .NET web application. There still fails, even after placing into the path directory MSVCR100D.dll requested before.

Sounds like a missing redistributable package for Visual Studio 2010. Please install it on the target machine:

Copying DLLs from that package is not a good idea! Since you are running a 32bit application you need the 32bit redist. package.

It must be this issue. You can find some stuff in the internet talking about this missing DLL:
