Hi Carlos,
I tried to hardlink the folder, as it worked previously. I got it to work with a "test script", directly via .bat or via command prompt. However, when I try to run a simple simulation with GiD, it shows the error I attached. Looking inside "applications" folder, I can only see a file named "applications_interface.py", I don't know if it is related but... Well, I can see plenty other folders and files inside the "kratos" folder downloaded using GiD.
Also, shouldn't I change other files? Like the one in: "\GiD 12.0.8\problemtypes\kratos.gid\python"?
