This article was created in response to a support issue logged with K2. The content may include typographical errors and may be revised at any time without notice. This article is not considered official documentation for K2 software and is provided "as is" with no warranties.

This content does not infer that the product, component or feature is supported, or that the product, component or feature will continue to function as described herein.


This issue can be caused due to a missing value in the CategoryPath for the apps in [dbo].[com_K2_App_Framework_Core_SmartObject_RegisteredApp] table.

Before You Begin

If you have not deleted the 4.7 apps after the upgrade to K2 Five 5.1, updating the CategoryPath with the correct value will allow the app to be removed from the Workspace > Published Apps page correctly.

How-to Steps

Once you have deleted the 4.7 App from the Workspace > Published Apps page, and by removing the entry  associated to the app that you deleted from the [dbo].[com_K2_App_Framework_Core_SmartObject_RegisteredApp] table, will allow the 5.1 app to be installed and updated successfully.

Please make sure to stop the K2 Service, and back up the K2 DB, prior to removing the entry from the K2 DB.
