scvmm version (2008 R2, 2012 or 2012 R2) using powershell

Hi experts,

I want to get the SCVMM version (2008 R2 or 2012 or 2012 R2) installed in my Windows Server using powershell.

I used 'Get-SCVMMServer' cmdlet. But it is giving (for SCVMM 2012) as,

ServerInterfaceVersion                 : 2.1.0

How is this useful?

Is there a way to get the SCVMM version using powershell or script?

Thanks,

Saleem
