    Connection failed on NPrinting engines

    Paul Wu

      Hi All,


      I just installed a Nprinting Server 17.3.1 and Engine on a server, I encountered “Connection failed on all NPrinting engines”  in the connection status and "Error request has been purged due to connection errors" in the Cache Status when create my first connection, checked the engine status is Online, and my account id also has the QlikView user cal, I also tested the local path but it raised the same error.




      Checked the Engine log file, found the below error information.


      Error while trying to add a resolver for connection navigator=qlikview;documentpath=qvp://xxx/xxx.qvw;username=xxx\xxx;encryptedpassword="xxxx".

      ERROR: An exception was thrown while invoking the constructor 'Void .ctor(Engine.Navigator.QlikView.QlikViewConnectionString, Engine.Navigator.QlikView.IQlikViewPool)' on type 'QlikViewContentNavigator'. ---> Exception has been thrown by the target of an invocation. (See inner exception for details.) Inner exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.BadImageFormatException: Could not load file or assembly 'Engine.Navigator.QlikView, Version=, Culture=neutral, PublicKeyToken=aa3e5cc00a2bd1f0' or one of its dependencies.


      Could you please help?


      Thanks a lot!
