Enterprise Library 4.1 error

When I try to run a WCF method an exception is raised and throws the below error.

The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionPolicyImpl, ExceptionHandlePolicy]) failed: The type 'Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.LoggingExceptionHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' cannot be resolved. Please verify the spelling is correct or that the full type name is provided. (Strategy type ConfiguredObjectStrategy, index 2)

I cannot upgrade to the latest version of MS EL 6.0 because our project heavily uses Composite Web which is obsolete now.

Is there any way to resolve this issue
