How to resolve the Add-PSSnapin Microsoft.TeamFoundation.PowerShell and Get-TfsChildItem error?

Below is the PowerShell Script that I am using to download the folder from TFS 2013 Update 4 to my local machine but i am getting some exception which I have copied below the code.

$AutoDeployDir = "$/Intel/Installscript/Utility Scripts"
$deployDirectory = "C:\powershell scripts\New folder\Demo TFS Code"

# Add TFS 2013 dlls so we can download some files
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.Client")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.TeamFoundation.VersionControl.Client")
$tfsCollectionUrl = "http://stptfs2013dbsvr:8080/tfs/intelcollection"
$tfsCollection = New-Object -TypeName Microsoft.TeamFoundation.Client.TfsTeamProjectCollection -ArgumentList $tfsCollectionUrl
$tfsVersionControl = $tfsCollection.GetService([Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer])

# Register PowerShell commands
Add-PSSnapin Microsoft.TeamFoundation.PowerShell

# Get all directories and files in the AutoDeploy directory
$items = Get-TfsChildItem $AutoDeployDir -Recurse -Server $tfsCollection

# Download each item to a specific destination
foreach ($item in $items) {
    # Serverpath of the item
    Write-Host "TFS item to download:" $($item.ServerItem) -ForegroundColor Blue

    $destinationPath = $item.ServerItem.Replace($AutoDeployDir, $deployDirectory)
    Write-Host "Download to" $([IO.Path]::GetFullPath($destinationPath)) -ForegroundColor Blue

    if ($item.ItemType -eq "Folder") {
        New-Item $([IO.Path]::GetFullPath($destinationPath)) -ItemType Directory -Force
    }
    else {
        # Download the file (not folder) to destination directory
        $tfsVersionControl.DownloadFile($item.ServerItem, $([IO.Path]::GetFullPath($destinationPath)))
    }
}

Exception that occurs is:

Add-PSSnapin : The Windows PowerShell snap-in 'Microsoft.TeamFoundation.PowerShell' is not installed on this computer.

Please make sure you have fully installed the TFS Powertools.

By default it doesn’t install the PowerShell CmdLets. If it is, just install it and then the issue will be gone.

Another possibility is that the PowerShell Snap-in is stored in the inconsistent registry with the OS version (32bit/64bit).

PowerTools installer is 32bit, on 64bit machine, it will write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell\1\PowerShellSnapIns, but not to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns.

Reference this similar thread for details: TFS Power Tools 2008 Powershell Snapin won’t run in on 64-bit in Windows 2008 R2?
