Update the DICOM viewer

The DICOM viewer automatically checks for updates. If an update is available, you will be asked to download the latest build of the DICOM viewer. Make sure that you close ALL windows of the DICOM viewer before installing the update.
The default period between update checks is 30 days. You can change this in the settings of the DICOM viewer, go to the General-tab.

Force an update check via the menu of the DICOM viewer, 'Help / Check for updates'.
