Problem to simulate an entity in VHDL

[PedroJServian]

Good afternoon colleagues,

I write to you as I have had a problem with the Simuation Waveform Editor of Quartus Prime Lite Edition. I am beginner in programming with this environment and I wanted to do the same thing as the guy in this short youtube tutorial: https://www.youtube.com/watch?v=1W6Aw6sZCjo&list=PLc3Oyld0v-1i4rhkFrwxb5GSfIoAQcYuE&index=4 

The code I have written for this entity is the followin one and it compiles well: 

library IEEE;
use IEEE.std_logic_1164.all;

entity prueba is 
   port (
    A: in std_logic;
    B: in std_logic;
    Y: out std_logic
   );
end entity;

architecture dataflow of prueba is
begin 
	Y<= A xor B;
end architecture;

What I wanted to do is to test the code with the University Program VWF and I did the same steps as the guy in the video. The problem appears when I Run the simulation and I get the following error message: 

**** Running the ModelSim simulation ****

c:/intelfpga/23.1std/questa_fse/win64//vsim -c -do prueba.do

** Fatal: Failed to initialize licensing environment. License environment not set correctly.

Unable to checkout a license. Vsim is closing.

** Error: Invalid license environment. Application closing.

Error.

I really don't know what could be happening. I would appreciate if you can help me

@PedroJServian, the problem has nothing to do with your VHDL code.  As the error messages clearly indicate, you haven't correctly set up your Questa license.

For detailed information on setting up the Questa license, see:

Hello

You could also verify the specifics of the license for Questa here.
