K2 4.7 February 2017 Cumulative Update Fix Packs

K2 May 2017 Cumulative Update

This article has been archived, and/or refers to legacy products, components or features. The content in this article is offered "as is" and will no longer be updated. Archived content is provided for reference purposes only. 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.


See KB001421 for the latest released Cumulative Update.

The K2 4.7 February 2017 Cumulative Update contains updates and fixes for issues reported in K2 4.7 products. K2 recommends keeping your K2 environment updated by installing the latest cumulative update, and that you test this update before you deploy to a production environment.



Prerequisites and Dependencies

This cumulative update is only compatible with K2 4.7 products (e.g. K2 blackpearl 4.7, smartforms 4.7 and K2 for SharePoint 4.7). Because cumulative updates are cumulative, each new cumulative update contains the updates and fixes that were included with previous cumulative update releases. The cumulative update does not require any previous cumulative updates or fixes to be installed, and no additional cumulative update is required to fully patch a K2 environment. If you have previously installed individual hotfixes that are included in this cumulative update, those hotfixes will not be removed or modified unless a newer version of the hotfix is available in the cumulative update.

Before you install this cumulative update, please check the K2 Product Releases and Build Numbers article to verify that this is indeed the latest available cumulative update.



Obtaining and installing the update

May 2017 is the latest released cumulative update see KB001888 for download details.

To install the cumulative update, run the cumulative update installer on every machine in your environment where a K2 product or component is installed, including desktop machines which have K2 Studio or K2 Designer for Visual Studio installed. The same installer is used to update the specific K2 products and components that are installed on that machine.
