install exit on chocolatey

[moldach]

I right click command prompt and select run as administrator before typing the command: powershell -NoProfile -ExecutionPolicy Unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://raw.github.com/webcoyote/linux-vm/master/INSTALL.ps1'))

It's exiting on an error:

It says choco is installed but nothing happens? Do I need to run a choco command next?
