Matlab 2007 Mex Function

Hello, Actually i am using a laser sensor and, it is working with matlab 2007 but not working with the latest versions of matlab, the company also told me that they have designed the code in matlab 2007, but i dont know that why its not working in latest versions of matlab, when i try to run the code its saying that their is some library file that is not found in latest versions of matlab, but its working fine with matlab 2007.

     The warning message that i am getting in latest version is:
Warning: A loader file was supplied that was built with a previous version of MATLAB that will not be supported in future versions of MATLAB. > In loadlibrary at 438 In FZSDKComm at 224 In SDKComm at 54 In InitSDKComm at 100 In OpenCamera at 24 In TOFExample at 31

Warning: Shared libraries are not supported on this platform. Functions that do not have a mexFunction signature may have unpredictable results.

 So please help me to solve this issue

Are you on a 64-bit machine? If yes, do you know if the binaries you were provided are also 64-bit? You can run "mexext" at the MATLAB prompt to find out whether you have a 32- or 64-bit version of MATLAB. The binaries must match the architecture of the MATLAB installation.
