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?
