Unable to run simulink dsp FFT block on target pc using simulink real-time.

Hello,

I am trying to do a real-time FFT operation on my target pc. I can run many different sorts of models using my set-up. But when i try to include the FFT block from the DSP toolbox, the model will not run. The following error is given: 'Unable to find library: dspfft.dll'

After some digging i found that using packNGo you can inlcude libraries in the model, but when i follow the procudere as given in the link below, it doesnt work.: http://blogs.mathworks.com/simulink/2008/11/26/wheres-the-code/

Now i get an additional error, where simulink searched my temp folder for the missing .dll's, but is unable to find them.

Since this is a mathworks toolbox (2014b 64-bit), i don't think these errors should occur. Does anyone know how to solve this?

Thank you in advance, Dennie
