I just did a fresh installation of Anaconda 2018.2 on Windows 10. This anaconda version uses python v3.7. While running conda for updating conda update conda, I
conda update conda
What worked for me was to copy these files from Anaconda3/Library/bin to Anaconda3/DLLs :
libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
