Why do I get segmentation fault when I try to start an exe compiled by mcc?

Hi,

I wrote an application with a gui to acquire data from an external device. In addition I use a dll to communicate with extrenal hardware. It works proper if I start the gui in Matlab.

Thus if I create an .exe aplication with mcc and try to start I got a segmentation violation fault.

On Win XP system the exe works fine.

I use MATLAB Version R2010b Service Pack 1 (32 Bit),Compiler 4.14.1., Data Acquisition Toolbox 2.17 on Win7/64Bit.

Here is a part of the stack trace:
