Altera SDK for OpenCL and ModelSim Installation

Hi,

I downloaded Altera SDK for OpenCL, version 15.1 which includes Quartus Prime software and devices (Linux edition). when I go through installation process it shows that I can also install ModelSim Altera starter Edition and ModelSim Altera Edition using this package. I check them to be installed, but at the end I could not find any folder containing ModelSim executable file such as VSIM. I used to install Modelsim separately and configure vsim as a simulation tool inside Qurtus II. But by this new package for OpenCL I cannot find the file. Does it mean that those check boxes in the installation process are wrong or mybe the name of executable file for ModelSim has been changed so I cannot find it?!
