    Hello,

    I have tried to run a model using cplex (the same model works for my colleague), but I receive the following error message after all the constraints have been created:
    --
    2020-28-Oct 11:54:42.470 Defined model objective.
    NEMO encountered an error with the following message: could not load library "c:\NemoMod\cplex.dll"
    The specified module could not be found. .
    --

    My system info is below. I installed LEAP and NEMO, and am running LEAP as admin user on my laptop. I did have some issues installing NEMO before so I wonder whether there could be a conflict arising somewhere.

    Update: I have tried running the optimization exercise with NEMO using another solver (i.e. not CPLEX) and it works fine. I also tried with osemosys(CPLEX) and it worked fine. The only one that appears not to work is NEMO(CPLEX). 

    Further update. I tried reinstalling NEMO while having CPLEX already installed and that appears to have fixed the issue.

    Thanks,
    Jonathan

    Hi, Jonathan -

    If you're now running LEAP as an admin user, I would just reinstall NEMO while logged into Windows as that user.  There's no need to uninstall NEMO first.  That should fix this problem, which appears to be due to the original issues you had installing NEMO.

    Thanks,

    Jason
