Cannot install pypy using conda-forge on Windows 10

[nlhnt]

Sorry if this is a wrong place to report this issue. Conda page says the package is compatible with any arch (noarch) in version v7.3.4.
Trying to install pypy using conda and -c conda-forge fails.
To reproduce:

conda create --name pypy_env
conda install -c conda-forge pypy

Output:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

PyPy on conda-forge is not yet available for windows. Hopefully once PyPy releases a reliable 64-bit windows version it can be supported. xref conda-forge/pypy3.6-feedstock#39
