I have an old optimization from 2 years ago that uses CPLEX 12.9 and ODH_CPLEX 4.0. I want to change the solver to CPLEX 20.1 (which is available in AIMMS 4.81). However, the list of AllSolvers does not include the new CPLEX. (nor ODH-CPLEX), so I cannot change the default to the new version. Is there somewhere else in the model that need to be updated for the list of solvers to update?
