    What have you tried? This is just a standard .NET error letting you know that it could not find the Web 8 version of Tridion.ContentDelivery.Common.Interop. So apparently you don't have Web 8 installed on that website. Commented Jan 22, 2016 at 10:18
  • what provider did you use? although from the error message I indeed would think you used the Web 8 provider but like @PeterKjaer mentions, you are missing the correct Web 8 DLLs Commented Jan 22, 2016 at 10:32

It's trying to load the Web 8 version of Tridion.ContentDelivery.Common.Interop and failing. So it looks like you don't have SDL Web 8 installed on that website.
