Error using DLL file

Good day to all,

I am trying to Import a DLL file using MATLAB Version: 8.1.0.604 (R2013a). After running the M file i get the following Errors:

Error using loadlibrary (line 419)
Building EbusAccess_thunk_pcwin64 failed.  Compiler output is:
cl -I"C:\Program Files\MATLAB\R2013a\extern\include"   /W3  /D_CRT_SECURE_NO_DEPRECATE /D_SCL_SECURE_NO_DEPRECATE

 Error in onStart_eBUS (line 3)
    loadlibrary EbusAccess.dll EbusAccess.h;

I have look at the following : http://de.mathworks.com/matlabcentral/answers/47641-mex-compilation-error-in-windows .

As my error is with the Header file, i cant simply rename the file and continue. Following is my Compiler configuration:

CompilerConfiguration with properties:

             Name: 'Microsoft SDK'
     Manufacturer: 'Microsoft'
         Language: 'C++'
          Version: '7.1'
         Location: 'C:\Program Files (x86)\Microsoft Visual Studio 10.0'
          Details: [1x1 mex.CompilerConfigurationDetails]
       LinkerName: 'Microsoft SDK'
    LinkerVersion: '7.1'

Please guide me in the direction so i can solve the error.
