Mfix 20.1.2 install error

Hi, I am trying to install mfix-20.1.2 but the following error occured.
I found some similar questions here but even after I refreshed the page I couldn’t fix it.

C:\Users\Soohwan>conda create -n mfix-20.1.2 mfix=20.1.2 mfix-doc=20.1.2 mfix-gui=20.1.2 mfix-solver=20.1.2 mfix-src=20.1.2 -c https://mfix.netl.doe.gov/s3/83a029b6/84410c63830e338913fe4287d097c5e9/conda/dist

An unexpected error has occurred. Conda has prepared the above report.

I just tested the Windows installation; it worked for me.

Could you try refreshing the Download page, and trying the command again? The download token may have expired.

Alternatively, you could download the source tarball and try installing with Pip.
