GAMS Model Error when scenario solve

[Bomi-Kim-96]

I am studying on MESSAGE-ix model by installing v3.4.0 and running westeros tutorial.

However, while running scen.solve() on 'westeros_flexible_generation.ipynb', There was a problem with a GAMS error(code 3: execution error) .

And there is no problem with the GAMS license, Any suggestion on how to solve it? I attached the error message and message version.
