When deploying a package created on K2 5.0 to a K2 5.1 environment, the legacy workflows encounter an error:
This workflow was created by a 'Thick Client Workflow Designer (K2 for Visual Studio, K2 Studio)' that is not supported on the target environment.
The environment was upgraded from K2 4.7 to K2 Five so it does have the legacy workflow designers (K2 Studio, K2 for Visual Studio) installed.
The 'ThickClientDesignTools' feature needs to be enabled to allow deployment of thick client artifacts.
Please run the following query to enable ThickClientDesignTools in the K2 Database:
UPDATE [K2].[HostServer].[Feature] SET [IsActive] = 1 WHERE Featurename = 'ThickClientDesignTools'
