Problem accessing SQL Server from PowerShell - sql-server

Question

I'm trying to implement a backup management script i found at http://sev17.com/2011/03/restore-and-relocate-database-files-using-powershell/
The article says it depends on SQLPSX version 2.3.2.1 or higher - I have the most current version.
attempting to execute this line:
$server = get-sqlserver $sqlserver
results in:
New-Object : Cannot find type [Microsoft.SqlServer.Management.Common.ServerConnection]: make sure the assembly containing this type is loaded.
At C:\Users\...\Documents\WindowsPowerShell\Modules\sqlserver\SQLServer.psm1:68 char:24
+ { $con = new-object <<<< ("Microsoft.SqlServer.Management.Common.ServerConnection") $sqlserver }
result of get-module -listAvailable

RE: SMO
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended")
results:

Answer 1

Make sure the Assembly containing the Microsoft.SqlServer.Management.Common.ServerConnection type (which I think is Microsoft.SqlServer.ConnectionInfo) is loaded first:
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.ConnectionInfo")

Answer 2

For me works with
Import-Module -Name SqlServer
It could stay in script
NOTE:
Windows Server 2016
Before I have installed
Install-Module -Name SqlServer
With [Reflection.Assembly]::LoadWithPartialName works only on windows 10 for me.

Answer 3

I realize this is just about the worst answer ever but...
Seems like there might be something wrong with your SMO or something. You could try loading SP3 for SQL 2008 or just try re-installing SSMS 2008. Installing the 2008 R2 version of SSMS could be an option as well.
Again, not the greatest answer in the world but might be worth trying.

Answer 4

The powershell components are only installed if you have powershell 2.0 installed at the time of SSMS setup. Powershell is normally already setup on the machine unless you are using Windows Server 2008. Ensure that powershell 2.0 is installed before installing SSMS.

Answer 5

$sc = New-Object Microsoft.SqlServer.Management.Common.ServerConnection
Error:
New-Object : Cannot find type [Microsoft.SqlServer.Management.Common.ServerConnection]: verify that the assembly containing this type is loaded
For this issue ,
Please Ensure micro soft sqlserver management object 2012(x64)is installed.
and go ahead check the dll files if present in given path "C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies"
