Keep RadarOpus running smoothly

Zeus Soft’s November notice asked users to update to RadarOpus 4.2.7 as soon as possible. Recent operating system updates, particularly on Windows but also on Mac, could prevent RadarOpus from starting. The notice stated that version 4.2.7 resolves this issue and recommended updating even if the program was still working normally.

Before installing an update today, check the release and system requirements on the official RadarOpus downloads page. If you use an older version or a Windows ARM computer and are unsure which installer applies, ask Zeus Soft support or contact Radar UK.

1. Back up your patient data

If you have patient data stored in RadarOpus, always make a backup before updating.

  • Already using 4.2.x? The November notice directed users to the small update for their operating system.
