Matlab - Simulation Interface toolkit

Hola a tod@s!

Actualmente estoy realizando un programa con Simulation Interface toolkit, con la version de Matlab R2012a(64bists) y el Labview 2012(32bits), y en matlab tengo el siguiente problema:

>> cd C:\SimulationInterfaceToolkit\
>> NISIT_AddPaths(2012)
SIT: Added paths for Simulation Interface Toolkit Version 2012
>> cd C:\SimulationInterfaceToolkit\2012\Lib\
>> ls

. R2007b
.. SITsServer.dll
NISITServer.dll nisit_set_param.m

>> NISITServer
Undefined function or variable 'NISITServer'.

>> NISITServer.dll
Undefined variable "NISITServer" or function "NISITServer.dll".

>> loadlibrary NISITServer.dll
Error using loadlibrary>lFullPath (line 587)
Could not find file NISITServer.h.

Error in loadlibrary (line 220)
header=lFullPath(header);

>> loadlibrary SITsServer.dll
Error using loadlibrary>lFullPath (line 587)
Could not find file SITsServer.h.

Error in loadlibrary (line 220)
header=lFullPath(header);
