PS Remoting Protocol Version Mismatch - powershell

Question

I have a disconnected session on Win7 Embedded SP1 32 bit station. I am trying to connect to that session. When I attempt to connect I get an error that suggests PSRemotingProtocolVersion mismatch. I can see my Windows 8.1 station has version 2.3 and the Win7 station has 2.2. How can I correct this issue so I can connect to the disconnected session?
Here is excerpts from my session...
PS C:\> Get-PSSession ef-pos-01.faculty.example.org
Id Name ComputerName State ConfigurationName Availability
-- ---- ------------ ----- ----------------- ------------
1 Session3 ef-pos-01.fa... Disconnected Microsoft.PowerShell None

Connect-PSSession : The connect operation failed for session Session3 with the following error message: Connecting to remote server

the protocolversion 2.3 that is negotiated by the client computer. Make sure the client computer is compatible with the build 6.3.9600.16406 and the protocol

Answer 1

I had this problem connecting Windows 10 (PS 5) to Server 2012 (PS 3). I could create the session and do whatever, but couldn't reconnect to it, even from the server. Likewise I could create and reconnect on the server (to localhost) but attempting to connect from my computer failed and broke the session.
I resolved this by installing WMF5 on the server to bring it up to PowerShell 5, is now running smoothly.
