Errors when Starting Agents in PCo 15.0 SP3

[Former Member]

We are in the process of upgrading to PCo 15.0 and are getting the following error when starting an agent.  We used the same configuration and setup using PCo 2.3 with no issue but we are having issues with PCo 15.0 SP3. This issue is happening on both DA and HDA agents.  Has anyone see this before:

1910     Manufacturing Fault: REASON = FileNotFoundException

Could not load file or assembly 'WebSocket, Version=15.0.3.2284, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.; SEVERITY = Fatal

STACK TRACE:

    at SAP.Manufacturing.Connectivity.Protocol.Custom.PCoQueryListener.Start()

   at SAP.Manufacturing.Connectivity.AgentBase.InitializeProtocol()

   at SAP.Manufacturing.Connectivity.AgentBase.Start()

Thanks,

George

HI George,

Re-apply the PCo Installer, expand the list of installation items, and scroll down to Additional Components to select Websockets, and deploy. That should correct your issue.
