Microsoft’s upcoming discontinuation of IE11 has signaled to us that it makes sense to prioritize other web browsers over continuing to support IE11. This applies to all design-time tools we provide as well as the end-user runtime experiences, such as Management and Workspace. You will be unable to open K2 tools using IE11 once you upgrade to Nintex K2 Five (5.5).
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.
