Overview

Following installation of the February and March 2020 Microsoft cumulative security update for Internet Explorer, Enterprise Console will fail to launch and crashes with the following unexpected error:

This security update has already been released to customers who have a Microsoft ESU license for Windows 7 and Windows 2008 R2 and is planned for release to remaining operating systems in March 2020.

Please Note. This issue will only cause the Enterprise Console to not open correctly.  All other functionality is working correctly; meaning:

• All Endpoints are still functioning as before the error occurred
• Endpoints will continue to receive security and product updates
• All other Enterprise Console functions (such as policy delivery) are still working as expected
