Mfix 19.1 not installing

I am trying to install mfix 19.1

I installed anaconda, the latest 2019 version and when I try the command “conda env create -n mfix-19.1 mfix/mfix-win64” I get

SpecNotFound: mfix/mfix-win64 was not found on anaconda.org.
You may need to be logged in. Try running:
anaconda login

I am already logged in to anaconda

Did the 18.1 installation require an anaconda.org login. Because I first tried the installation 19.1 with my prior version of anaconda I couldn’t remember my anaconda login so when I tried to update my login and reset my password anaconda could not find me via my email address.

Note that the conda command changed; the environment is named mfix/mfix-19.1-win64 not mfix/mfix-win64

conda env create -n mfix-19.1 mfix/mfix-19.1-win64

Please try again with the above command.

I belatedly realized that anaconda.org doesn’t let you keep multiple versions of the same environment; so we need to keep the MFIX version number in the environment name. (I plan to setup an mfix-18.1 environment too; for folks who want to install older archive versions of MFIX.)

You do not need an anaconda login; the environments are public. (I just removed the ambiguous mfix-win64 one).
