We’re informing all our customers that as of the release of Nintex K2 Five (5.5), Nintex will no longer include Internet Explorer 11 (IE11) on our list of supported browsers. You will be unable to open K2 tools using IE11 once you upgrade to Nintex K2 Five (5.5). This applies to all design-time tools we provide as well as the end-user runtime experiences, such as Management and Workspace.
Microsoft’s upcoming discontinuation of IE11 has signaled to us that it makes sense to prioritize other web browsers over continuing to support IE11. We will focus on optimizing Nintex K2 Five tools for use with other modern browsers which will make for a superior overall experience for you.
As part of this change, the Silverlight-based workflow designer will no longer be supported. Accessing the Silverlight-based workflow requires a browser that supported the Silverlight plug-in, which is only IE11. Therefore, when K2 Five (5.5) blocks IE11 from use, the Silverlight-based designer will also no longer be available.
If you must continue to use IE11 or edit your workflows using the Silverlight-based designer, you must remain on Nintex K2 Five (5.4).
Attached to this article are SQL scripts that you can run against your K2 database to find out which workflows are deployed from the Silverlight-designer. There are four scripts:
If you have Silverlight Designer-based workflows that are still actively being run (started dates in the past month), you may want to rewrite those workflows in the new workflow designer, so that you can continue to edit and maintain those processes.
The following steps can help you plan your removal of Silverlight dependencies, to prepare for upgrading to Nintex K2 Five (5.5).
If you need assistance in any of the above steps, Remote Services or our Professional Services departments are available to help. Reach out to your Nintex account representative for more details.
