In my case, I could not install any package and got a similar error. The issue was solved as I unchecked the "Microsoft and .NET" under "Machine-wide package source":

I hope this can be help someone.

I got a similar problem with another package in Visual Studio 2013, I cleared the NuGet package cache with the option "Clear Package Cache" and it works now.

Change source according to visual studio version

NuGet feed v3 (VS 2015 / NuGet v3.x): https://api.nuget.org/v3/index.json
NuGet feed v2 (VS 2013 and earlier / NuGet 2.x): https://www.nuget.org/api/v2

I just ran into this myself. The reference to WebActivatorEx didn't work. You'll have to do it manually. The file is in the packages directory.
