Initialisation Error Loading the Deployment Workbench in Windows Server 2012
When you deploy the Microsoft Deployment Toolkit to Windows Server 2012 you may come across the following error when trying to load the Deployment Workbench: “Initialization Error: PowerShell is required to use the Deployment Workbench”
As you know PowerShell comes as standard in Server 2012, this error is to do with the execution policy, to resolve it, simply run the PowerShell console as an Administrator and issue the following command.
Set-ExecutionPolicy RemoteSigned –Scope CurrentUser
If you want it for the full system then just drop the -Scope parameter.
