No SQL Server PowerShell snapin installed despite installing SQL Server
In SQL Server 2012 the PowerShell functionality delivered by the product came in the form of a PowerShell module, so therefore you no longer need to work with the snapins.
To consume the SQL Server PowerShell module, you simply need to do this:
Import-Module "sqlps"Or if you are using PowerShell v3+ then you just need to reference a member of that module and it'll be automatically loaded in.
