title: InvalidArchiveError when installing openssl-1.1.1g through Anaconda 4.7.12 on Windows 10
body: <p>I am trying to install requests module, and openssl keep causing the InvalidArchiveError.
  I am using conda 4.7.12, python 3.8.2, on Windows 10 operating system. I had the same issue when installing other packages requiring openssl-1.1.1g. I have followed the advice from the error message to delete and re-download 'openssl-1.1.1g-he774522_0.tar.bz2', but I keep getting the same error.
  Is this version of openssl broken or something? Any help will be greatly appreciated. </p>
