1. Install Python 3.5 using the official Windows installer 2. Get a shell 3. python -m ensurepip (because the installer didn't install pip for me -- is that another bug? I thought the installer was supposed to run ensurepip for me? Is it fallout from bug 25117?) 4. python -m pip install virtualenv (gets me version 13.1.2) 5. python -m virtualenv env I expect: a virtualenv in ./env I get: a GUI error dialog saying "The program can't start because VCRUNTIME140.dll is missing from your computer."

virtualenv fails to copy vcruntime140.dll. Use the standard library's venv module instead.

Thank you for the pointer! It's hard to tell which software component is at fault when multiple components fail to collaborate. I cannot choose to use venv because I'm actually using tox, which runs virtualenv for a bunch of Python versions, some of which don't even have venv. I've filed a virtualenv bug: https://github.com/pypa/virtualenv/issues/796
