A: No. Hotfixes are sequential. If you need fixes from Hotfix A and Hotfix B, you must install A, then B unless Schneider issues a "Rollup Hotfix." Q2: Will this hotfix affect my existing runtime on a production HMI? A: No. It only changes the development software. However, after you re-download a project using the hotfixed software, the runtime on the HMI will be updated. Validate offline first. Q3: Can I uninstall the hotfix? A: Not directly. You must uninstall Vijeo Designer entirely, then reinstall 6.2 Base and SP12. Therefore, always create a system restore point before installing the hotfix. Q4: Does this hotfix support Windows 11? A: Schneider’s official stance is Win10 64-bit. However, many users report stable operation on Windows 11 Pro (22H2 or later). The hotfix specifically fixes a Win11 compatibility issue with the USB driver stack. Part 8: The Alternatives – Should You Skip the Hotfix?
