VMware.VimAutomation.VdsComponents

I am looking for a script thats will list the security policy for the vDS Portgroups. I installed the vDSPowerCli but keep getting this error. Works for 32bit powershell, but not on 64bit.

Add-PSSnapin : The Windows PowerShell snap-in 'VMware.VimAutomation.VdsComponent' is not installed on this machine.

At E:\Scripts\HealthCheck - Pramod\dvswitch_1.ps1:1 char:13

+ Add-PSSnapin <<<< VMware.VimAutomation.VdsComponent

+ CategoryInfo : InvalidArgument: (VMware.VimAutomation.VdsComponent:String) [Add-PSSnapin], PSArgumentExcepti

on

+ FullyQualifiedErrorId : AddPSSnapInRead,Microsoft.PowerShell.Commands.AddPSSnapinCommand

Any solution?
