@paola-castillo, I used Google Translate to translate what you wrote as:

"Hello, I downloaded and installed the program, but the pop up where the token is put never appeared, and I have not been able to link my computer, how else can I do this process to be able to link my computer?"

Assuming you're running Windows, you could run this command to run the agent in text mode in a cmd window with this command:

node %LOCALAPPDATA%\TRIGGERcmdAgent\app-1.0.25\resources\app\src\agent.js --console

You'll need to install Node JS first.
