Well, I even tried putting in the correct registry edits for the .Net, but still it won't work. Sorry.
My 17650.1001 has a setting there for it as follows - .NET Framework 3.5 (includes .NET 2.0 and 3.0) Windows Communication Foundation HTTP Actvation Windows Communication Foundation Non-HTTP Actvation Only the ".NET Framework 3.5" item is selected. Mine is an upgraded PfW 17134.1 that had .NET Framework 3.5 installed.
