This just happened, so some update has broken something. I saw this originally last year, but I can’t recall how I fixed it. Why would Julia/Atom get confused on what version of PowerShell I am running?

I’m on a Windows 7 Professional corporate machine, everything should be up to date.

What exactly causes the error (i.e. example triggering the error)? Is it from Atom or Julia.

I’ve seen this pop up sporadically, but never consistently unless it’s actually correct.  
Can you give me the ouput of `powershell $PSVersionTable.PSVersion` evaluated in the command line?

It triggers every time I start up Atom. It doesn’t if I start the command line version of Julia.

```
PS C:\Windows\System32\WindowsPowerShell\v1.0> 
$PSVersionTable.PSVersion

I noticed that the powershell dropped out of my path (yay corporate IT meddling again!) so I suspect that is part of the problem. Fixing that situation now.

…typing typing typing…

…and it’s fixed. I was launching powershell from a desktop icon which had the path hardwired. Launching it from the command line is the real test.
