How to insert path to get RTL Simulation In Quartus Lite 21.1

Hi,

I'm using Quartus Prime Lite Edition for project. In project I must do RTL simulation. But it can not launch the Modelsim software. It said the path to the location of the executables for the Modelsim software were not specified or the executables were not found at specified path.

How can i get RTL Simulation in Quartus Prime Lite Edition 21.1
