The Windows 10 update v2004, released May 2020, has a bug that prevents NX1884, Simcenter 3D 2019.2 (v1884), and all prior releases from launching; this includes the interactive launch in native, managed mode as well as invoking any NX session using external custom NXOpen applications. The bug also impedes a user to launch Teamcenter Visualization or any integration that uses the SOA Client, Foundation Viewer in RAC, and Tecnomatix.
KB4568831 (OS Build 19041.423) addresses the previously mentioned issues for Windows 10 v2004. Microsoft released KB4568831 (OS Build 19041.423) on July 31, 2020. Before installing this update, Microsoft strongly recommends you install the latest servicing stack update (SSU) for your operating system before installing the latest cumulative update (LCU). SSUs improve the reliability of the update process to mitigate potential issues while installing the LCU.
If you are using Windows Update, the latest SSU (KB4566785) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog.
