Issue

[LukeKaim]

This does not work on Conda 4.3.25. Is there any workaround?

Disclaimer on formatting, I cannot preview from work (weird firewall issues), so I apologize if it looks jacked up.

Not sure error what you were hitting, but I was unable to activate directories (and thus could not activate my install at C:\Continuum\miniconda3 like the Anaconda prompt does). I am not a PowerShell guru by any stretch (in fact, I pretty much don't know what I am doing, just started learning today) but I was able to work around it by doing the changing the activate.ps1 file:

The following patch should cover the issue, though it is not exhaustively tested and this was written by hand (diff tool is broken on my end).
