"Failed to load MWArray..." during building a .NET component with Type-safe interface.

I tried to build the example funtion (AddOne) from the MATLAB builder NE guideline, but it threw the following exception:

Exception in thread "main" C:\Users\[...]\AppData\Local\Temp\build1336735937405390249.xml:19: Failed to load MWArray assembly. Please make sure 'MWArray,
Version=2.12.1.0, Culture=neutral, PublicKeyToken=e1d84a0da19db86f' is
installed in the GAC.

I compiled the interface for exactly the same platform as the MATLAB (x86), the MWArray is in the GAC with the same properties. MATLAB and the Builder NE is R2012b.

Can anyone help me with this?

I am fighting the same problem with the same version of Matlab. On another computer I don't see this problem. I have already re-added to the GAC MWArray as well. Did anyone come out with any explanation?
