    Thanks for the post. Can you try to elaborate the scenario where this exception occurs for the applications that are already running with same assemblies please.

    This occured due to installing a custom feature with the dll in both locations. This same error also occured for a different reason after restoring a site collection from one web app to another in the same site collection. In the second case a simple IISReset fixed the issue.
