Thanks for the support. It worked!
I have a problem with updating MFIX. Whatever I do, I cannot update mfix packages, I even uninstalled and reinstalled Anaconda but it keeps reinstalling the previous version. I had two installations one with 18.1.3 (that I could not update to 18.1.5) that I had to remove finally, and the other one with 18.1.5 that I am trying to update now and failing. I am using Windows 10 and miniconda3. Could you help me with this issue please?
