What version of PowerShell do you have?
I saw that error before on machines with PoweShell < 4.

You can install it from here if you don't have it: http://www.microsoft.com/en-us/download/details.aspx?id=40855

You need a newer version of Powershell to use KVM. Core CLR will also not currently work on Windows 7, so you will not be able to switch to Core CLR.

Updating the Powershell worked perfectly! Thansk!
