Installing policy files and .NET assemblies for add-ons
If you are running Content Delivery Server Roles in a .NET Web application and you have WebForms, Online Marketing Explorer, or SmartTarget installed, on the machine on which your add-on is running you need to copy policy files and 2013 SP1 DLLs to your Windows assembly.
About this task
The policy files and Content Delivery DLLS are required to resolve DLL versioning conflicts and so enable the add-on to work with Content Delivery 2013 SP1.
