Exchange server 2013 Error Message When Starting The Exchange Management Shell

In Exchange Server 2013 you receive an error message when trying to use the Exchange Management Shell.

The error looks like this:

VERBOSE: Connecting to server Server01.
New-PSSession : [Server01] Processing data from remote server failed with the
following error message: Unable to determine the installed file version from the registry key
‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine’. For more information, see the
about_Remote_Troubleshooting Help topic.

To fix the problem and be able to use the shell you will need to install PowerShell 2.0 from the add features using server manager.

Note: Make sure your server has access to the internet to download the package.
