Hi, 

I am working upon a referencing issue, one of our projects depends upon the 'Episerver.Marketing.Connector.Silverpop' addon.

When this project is then referenced by Commerce Manager it is returning the following error:

Unable to find a module by assembly 'Episerver.Marketing.Connector.Silverpop, Version=4.2.0.0, Culture=neutral, PublicKeyToken=null'
Parameter name: moduleAssembly

The stack trace is as follows:

[ArgumentException: Unable to find a module by assembly 'Episerver.Marketing.Connector.Silverpop, Version=4.2.0.0, Culture=neutral, PublicKeyToken=null'

My understanding is that when this addon is initializing it is looking for the 'Episerver.Marketing.Connector.Silverpop' folder inside the modules > protected folder. After placing the folder there manually the issue is still occuring.

Has anyone experienced anything similar? or know a way to resolve?

Thanks
