Issue: You need to check your currently installed PowerShell version and upgrade to a newer version.
Solution:
1) Check the current version of Powershell
2) Upgrade PowerShell by downloading and installing the corresponding version of Windows Management Framework (WMF). For example if you want Windows PowerShell 5.0, then you would download Windows Management Framework 5.0 (at time of this writing, 5.1 which is currently in “preview” but will be officially released shortly).
