Downgrading Version of Python Offline with Anaconda

  anaconda, offline, python, version, windows

I have installed Anaconda 2020.07 (release notes claim that "Meta-packages for Python 3.6, 3.7, and 3.8 are also available") and by default, Python 3.8 was installed. I would like to install Python 3.7 offline instead using conda install python=3.7 --offline but Anaconda Prompt complained that "packages are not available for python=3.7"

What should I do?
