SharePoint 2013 Management Shell Cannot load Snap-In Issue Resolved

On a brand new production server after installing and configuring SharePoint 2013, running the SharePoint 2013 Management Shell produced an alarming error:

Add-PsSnapin : Cannot load Windows PowerShell Snap-In
Microsoft.SharePoint.PowerShell because of the following error: Unable to cast
object of type 'Microsoft.SharePoint.PowerShell.SPCmdletSnapIn' to type
At C:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\15\CONFIG\POWERSHELL\Registration\SharePoint.ps1:3 char:1
+ Add-PsSnapin Microsoft.SharePoint.PowerShell
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (Microsoft.SharePoint.PowerShell:St
   ring) [Add-PSSnapin], PSSnapInException
    + FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.Ad

I searched the web for an answer and found some posts in forums. Essentially their answer was to rebuild the server because they installed and reinstalled software and/or upgraded the operating system. In my case, this was brand new - there was no way this was because of an upgrade or software being installed incorrectly.

After trying to repair SharePoint 2013, running the Products Configuration Wizard, uninstalling/reinstalling SharePoint 2013, removing server roles, adding server roles, etc. etc. etc., I finally took a step back and figured out the problem.

I thought this must be an issue with PowerShell and not SharePoint - it turns out it was. To resolve this issue, all you need to do is uninstall and reinstall the Windows Management Framework 3.0.

Simply open the Control Panel on your server and click on programs:

On the Programs screen, click View installed updates:

Locate Microsoft Windows Management Framework 3.0 (KB2506143), right click the entry, and select Uninstall:


Run through the uninstall, restarting the server if directed.

Next, open browser and navigate to the WMF 3.0 download in the Microsoft Download Center. Download and reinstall Windows6.1-KB2506143-x64.msu:

Restart the server if directed. Run SharePoint 2013 Management Shell and the issue is resolved!!!
