Running IIROrder2 demo

Hi dears,

I need your urgent help please.

I'm trying to run IIROrder2 module which is in the Demos folder in the examples of DSP Builder, but the following error appears:

Error evaluating 'InitFcn' callback of block_diagram 'topiir'. Undefined variable "com" or class "com.altera.dspbuilder.simulation.Cache.createModel".

Thanks.

    This means DSP Builder is likely not installed properly.

    Try re-installing.

    DSP Builder 10.1 does not support 64-bit MATLAB. You need to install the 32-bit version of MATLAB.

    In addition you can't use DSP Builder 10.1 in conjunction with Quartus II 7.2.

    You should use Quartus 10.1. DSP Builder is installed as part of Quartus. It is only compatible with a Quartus that has the same version number.
