Symptoms

Whenever an attempt was made to access the viewflow from workspace or a link a redirect was made to download Silverlight.
 

Diagnoses

The Silverlight issue was a red herring. The real issue was the web service that was migrated into the environment and host on the same port as the viewflow.
 

Resolution 

Reconfigured K2 to use a different port in IIS so as not to compete with the web service.
