The demo mode allows users to try out the DICOM Viewer using it without any functionality limitations for 14 days. The only requirement is connecting your computer to the Internet. After the 14 day trial period, the DICOM Viewer will go inactive. To continue working wuith it, you must purchase a license. The trial period for each edition is set separately.
A license key enables you to activate the DICOM Viewer versions released within a year of the key purchase. The versions released after the one-year period are not activated, but the trial period is available for them. To extend the activation period of the new versions for another year, purchase a subscription to updates.
Starting from version 1.11.0, specialized modules can additionally be connected to the Pro edition. Such modules are licensed and paid for separately. The main functionality remains available in the Pro edition.
