Symptoms

I am getting below error while trying to below K2 workflow from Visual Studio.

Note: We recently upgraded our server to 4.6.10. This is Sharepoint 2010.

Error Message:

Diagnoses

The K2 for Sharepoint Components were upgraded to 4.6.10 on both the Sharepoint WFE and Central Administration Server but the 'K2 for Sharepoint Configuration Wizard' had not been completed to upgrade, update and reactivate the K2 Features and Configuration Settings.
 

Resolution

After upgrading, updating and reactivating the K2 Features and Configuration the Integration Wizard and process deployment was successful.
