PowerShell: How do I install the Wave 8 DSC Resource Kit modules?

I am trying to set up a DSC Offload Server on a Windows 2012 R2 machine by following the following technical article:

http://technet.microsoft.com/en-us/library/dn249913.aspx

However, I just can't seem to get the modules to work. The installation instructions state:

To install all modules of the DSC Resource Kit, extract the content into

$env:ProgramFiles\WindowsPowerShell\Modules 

      

        
        
        
      

    

To confirm the launch of the installation Get-DSCResource

, to see that all resources on this page refer to the listed DSC resources.

So, I copied the contents of the "DSC Resource Kit Wave 8 10282014" folder into C:\Program Files\WindowsPowerShell\Modules

which now looks like this:

c:\Program Files\WindowsPowerShell\Modules>tree
├───cFileShare
│   ├───DSCResources
│   │   ├───VSAR_cCreateFileShare
│   │   └───VSAR_cSetSharePermissions
│   ├───Examples
│   ├───ResourceDesignerScripts
│   └───Unit Tests
├───xActiveDirectory
│   ├───DSCResources
│   │   ├───MSFT_xADDomain
│   │   ├───MSFT_xADDomainController
│   │   ├───MSFT_xADDomainTrust
│   │   ├───MSFT_xADUser
│   │   └───MSFT_xWaitForADDomain
│   └───Misc
├───xAdcsDeployment
│   ├───DSCResources
│   │   ├───MSFT_xAdcsCertificationAuthority
│   │   └───MSFT_xAdcsWebEnrollment
│   └───xCertificateServices
│       ├───DSCResources
│       │   ├───MSFT_xAdcsCertificationAuthority
│       │   └───MSFT_xAdcsWebEnrollment
│       └───Examples
[...]

      

        
        
        
      

    

Then I restarted the PowerShell console to reload $env:PSModulePath

which contains this by the way (added linewrap line for better readability):

PS C:\Users\Administrator> $env:PSModulePath
C:\Users\Administrator\Documents\WindowsPowerShell\Modules;
C:\Program Files\WindowsPowerShell\Modules;
C:\Windows\system32\WindowsPowerShell\v1.0\Modules\

      

        
        
        
      

    

Thus, everything here is invalid by default. However, get-module -ListAvailable

none of the above modules are simply listening, for example. xPSDesiredStateConfiguration

... Also, the cmdlet Get-DSCResource

does not return any of the resources that come with this module (especially the xDSCWebService

DSC resource I am looking for to configure the unload server).

If I manually copy the content xPSDesiredStateConfiguration\DSCResources\*

to one of the pod folders, I see the DSC resources. However, the installation of the pull-server script ( Sample_xDscWebService.ps1

) fails. Opening the editor, it shows a syntax error next to:

Import-DSCResource -ModuleName xPSDesiredStateConfiguration

      

        
        
        
      

    

I just can't figure out what I am doing wrong here. So how can I install the DSC Resource Kit?
