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.
At line:1 char:1
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.
