No snap-ins have been registered for Windows Powershell version 5

[Fazza]

I've just installed System Center Service Manager and I am now configuring it.

 

 

I've installed it on Server 2016 and I'm trying to run the following powershell command but I'm getting an error:

 

Add-PSSnapIn SMCmdletSnapIn

 

The error I get is the following:

 

No snap-ins have been registered for Windows Powershell version 5

 

I've not really played around with powershell much so do I have to register this snap-in first before the above command will work, if so how do I do that?
