The demo mode allows users to try out the DICOM Viewer using it without any functionality limitations for 30 days. The only requirement is connecting your computer to the Internet. After the 30 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.
Beginning with version 1.9.0, after the release of the product with the changed second number in the product version (the so-called minor version), you can re-activate the trial period. For example, a user who activated Lite edition version 1.9.0, but after the one-month period did not acquire a license, will be able to activate the trial Lite edition version 1.10.0 again to research its functionality. The same applies to the Pro edition.
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.
