NAG installation interferes with Juno REPL?

This is @ChrisRackauckas on a computer at a workshop. The issue on this computer seems to be coming from clashing with an installation of NAG on Windows. Trace:

using the REPL on its own seems fine, so I'm not sure what this is. sometimes the REPL still starts up, sometimes it throws something like this and crashes Atom

Disabling the powershell wrapper might work around the issue.
