There is another reason you might get the error "Server.CreateObject Failed". A COM Visible DLL does not behave the same as a regular .NET DLL when it is being loaded by COM. You can't expect it to load other DLLs that are sitting in the same directory as your DLL, or downloaded through the Nuget package manager. If you want to load other DLLs you have to register them in the global assembly cache (GAC).

If the assembly doesn't have a strong name then you won't be able to register it in the GAC.
