WD Sentinel - Media server

WD Legacy Products Sentinel Products

I can’t get Serviio installed.  

I downloaded WHS v1 (v0.6.1). Placed the downloaded MSI file in my Sentinel’s Software/Add-Ins shared folder.  Double clicked and I get the error message “Serviio Media Server for Windows Home Server requires Windows Home Server.”  

Has anyone actually installed this on the Sentinel.  If so, can you please give a detailed description of the install process?
