deployment fro a com object crashes matlab

Hello,

   As soon as I click on the build button, Matlab crashes. The same build work on another computer. This is an m-file compiled to create a COM dll. mBuild is using Microsoft Visual C++ 6.0 compiler. The Matlab version is 2007a. The m-file runs under Matlab. It is possible to develop a project under VS C++ successfully. The same computer has also VS 2008 and VS2010 Express with their C++ libraries but, "Mbuild -setup" does not detect these C++ libraries during the initial setup. The environment settings are the same between two machines.
