Virtual CRASH 6 Dependency Fix for Windows 11 Update 24H2
At this time, the Windows 11 version 24H2 update inappropriately alters certain software libraries, potentially affecting joint-coupled-object simulations (such as multibodies) in Virtual CRASH 6. While differences typically remain within acceptable tolerances, simulations may show differences when files saved before 24H2 are opened on 24H2 updated systems (or vice versa). Microsoft is aware of the underlying issue, but has provided no guidance on when a patch to 24H2 will be rolled out to fix this specific issue. Therefore, the Virtual CRASH Spring 2025 Software Update pro-actively removes dependencies on the affected libraries, aims to restore simulation reproducibility without waiting for Microsoft to issue a patch at some unknown time in the future, and limits exposure to (unlikely) future potential inappropriate software library modifications caused by Windows updates.
For now, we recommend pausing Windows updates until Microsoft resolves these and other widespread hardware and software compatibility issues affecting multiple applications including those from Autodesk and Ubisoft (learn more). If you’ve already installed 24H2, we recommend rolling it back to a prior version (learn more).
Note: Versions 5, 4, 3, and Public Safety are not affected by 24H2.
