Is your feature request related to a problem? Please describe.
The file browser doesn't work in powershell 2 agents and does not give a response to the user.
#67

Describe the solution you'd like
Starkiller should give a notification or popup message on the file browser that it is not compatible with powershell 2 instances.

Describe alternatives you've considered
We can build a different way to do the file browser that does not rely on "convertto-json" but that doesn't seem practical.
