I am trying to upgrade EPiServer on a Windows Server 2003 R2 Standart Edition. Deployment center has no problem installing.

When i open Deployment Center and navigate to "Uppgrade site with SQL Server database" and press "Run" i takes about 3 seconds before the message

"Error - The term 'New-EPiCMSWizard' is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again." and prosess fails.

When i run the command in Powershell, i get:

Windows PowerShell

PS C:\Documents and Settings\keauadm> Get-PSSnapin -r

I have tried to uninstall/install Deployment Center but no different outcome.

Am i missing something some snapins in  the powershell? if i do, how do i get the missing ones?

Hope someone can help me figure this out.
