Pyomo returns error using ipopt as a solver

[jdelamot...@gmail.com]

Hello everyone. I have just installed Python, pyomo and ipopt in a new computer, I have tried to run one of my older files to check if it Works, but when I do it, I get an error thtat I haven't seen before (see the first attached figure). 

I have installed pyomo as pip install pyomo and ipopt as conda install -c conda-forge ipopt.

I have also tried to uninstall ipopt as conda remove -n myenv ipopt, but I also get an error, (see second attached figure).

Ca anybody please tell me how to proceed now? Any help is appreciated.

Regards.
Jaime.

I have changed the CPU from an Intel to an amd, I don't know if that might explain what is going on.
