What steps should I follow or what is the MATLAB command that I should use in order to successfully load the dll file for NI's USB-8452 device?

Computer Specs: 64 bit Windows 7 OS; MATLAB R2013b; Compiler: Microsoft Visual C++ 2008 SP1

I have in a working folder the following files from National Instrument that pertains to their USB-8452 device: Ni845x.dll and ni845.h files. I attempted to load the functions found in the .h file as follows:

>> [a,b] = loadlibrary('Ni845x.dll','ni845x.h');

...but I am encountering errors. I am enclosing a snippet of the errors since there are about 48 pages of errors generated by MATLAB:

Type 'intkNI845XExportint32NI845X_FUNC' was not found. Defaulting to type error. Found on line 376 of input from line 375 of file ni845x.h

Error using loadlibrary (line 418) Building Ni845x_thunk_pcwin64 failed. Compiler output is: cl -I"C:\Program Files\MATLAB\R2013b\extern\include" /W3 /D_CRT_SECURE_NO_DEPRECATE /D_SCL_SECURE_NO_DEPRECATE /D_SECURE_SCL=0 /nologo -I"C:\Users\MATLAB Scripts" -I"C:\Users\MATLAB Scripts" "Ni845x_thunk_pcwin64.c" -LD -Fe"Ni845x_thunk_pcwin64.dll" Ni845x_thunk_pcwin64.c C:\Users\MATLAB Scripts\ni845x.h(371) : error C2054: expected '(' to follow 'kNI845XExport' C:\Users\MATLAB Scripts\ni845x.h(371) : error C2085: 'NI845X_FUNC' : not in formal parameter list

Are there any steps I can take in order to correct the errors I am encountering?

Thanks in advance for any suggestions.
