MFIX-19.3.0 installation failure

I am trying to install MFIX-19.3.0 on my computer but it gives me the following error. Please let me know if you know how to solve this problem.

Looks like the conda command is incomplete. Please try again with the “Copy to Clipboard” option on the download page, then paste into the conda prompt. The command should include your username and token (do not post it on the forum for that reason).
