Where are Paths for EDA Simulators?

I have Quartus II 10.1 (licence), when I want to perform simulations (functional and timing), it is required to fill the paths for EDA simulators.

I only found one EDA exist in my Quartus which is Modelsim (free). it location : C:/altera/10.1/modelsim_ase/win32aloem

Meanwhile, I could not find other EDA tools (such as Active HDL,LeonardoSpectrum, NCsim, etc) in folder : C:/altera/10.1/...

Are in my Quartus II include those EDA simulators beside modelsim? where to find them?

I need them to perform timing simulation since the Modelsim exist is a free one.
