c2000hostsci_rx.tlc doesn't exist

Hello everybody, i tried to build serial communication using C2000 launchpad to matlab like in this link : https://www.mathworks.com/matlabcentral/fileexchange/45124-motor-control-with-ti-launchpad/content/host_rx.slx

But, i got an error that says

The corresponding 'c2000hostsci_rx.tlc' file for the MATLAB S-function 'c2000hostsci_rx' in block 'SCI/SCI Receive1' must be located in the current working directory.

So, i tried to search the 'c2000host_rx.tlc' file in my computer, but there is no such file. Anyone know how to fix this problem? Thank you in advance.
