PIC16F877A Simulation in Proteus 8.6 won't show the output lights

Greetings,
I have a few question to ask regarding my circuit in Proteus 8.6. I’ve constructed a circuit that posted in this link –> https://electrosome.com/switch-pic-microcontroller-hi-tech-c/ . I also built the program using the Hitech C compiler using Mplab software. And then, when I try to run the simulation in the Proteus using the hex file I built in Mplab, it didn’t even say error or something like that, instead, the led in the circuit itself won’t light up (no error message in Proteus while I run the simulation). I already tried to reinstall all my programming and other software (mplab, proteus, hitech c). But, it doesn’t work. What should I do? This is really stressing me out. This website is the only one where I can study more about Embedded Programming.

Thank you.
