Simulink run error "Cannot activate configuration set" in R2012b

Hi, I received a model written in R2011b. My Matlab is R2012b. While trying to run the Simulink model, it immediately popped an error "Cannot activate configuration set 'Configuration1' Caused by: Unknown device name". However there is no Configuration1 - only 1 Configuration. Can you please help? Thanks a lot!!!!!

What setting do you have under the 'Hardware Implementation' pane on the Configuration Parameters window for "Device vendor" and "Device type"? It looks like the model has an invalid setting.
