Have double "No Python 3.7 installation detected" error

Your 3.7.1 install is for all users, and you're trying to install 3.7.4 just for yourself.

This is supposed to work, so I'm not sure why it isn't. I haven't had time to look more closely, but if you are able to install for all users (by going through the "Custom" install button) or uninstall 3.7.1 first, you should be fine.
