Found a solution: Installing 32 bit version of Matlab and try with this. Worked at first try!
More detailed: Win7 has 2 different folders for system .dlls
C:\windows\system32: Here are all the .dlls for 64-bit software and not for 32!
C:\windows\SysWoW64: WoW64 stands for "Windows on 64-bit Windows", and it contains all the 32-bit binary files required for compatibility, which run on top of the 64 bit Windows.
Using 32-bit version, Matlab will use the SysWoW64 files. And that is the rigth kernel32.dll which contains all the functions needed!
