Scroll Prev Top Next


Activation (trial license)


What is activation (trial license)?


Activation in trial mode allows you to use a fully functional version of RadiAnt DICOM Viewer during the evaluation period.


How often do I need to activate RadiAnt DICOM Viewer (trial license)?


The evaluation version expires after a predetermined period of time (displayed after activation).

After expiration, the installation needs to be reactivated for further evaluation.

Old versions may not qualify for the evaluation. In that case, you can purchase a license if you want to continue to use the old version or download the most recent version from RadiAnt's website and activate it in trial mode.


Activation (paid license)


What is activation (paid license)?


Product activation is the process of verifying the validity of a product's license. Once the product is activated, the user can access the software.

The product activation process protects both your rights as a consumer and the rights of Medixant as a software developer.

It verifies that you have installed genuine RadiAnt DICOM Viewer software and that the product has not been activated on more computers than those permitted by the EULA.


How often do I need to activate RadiAnt DICOM Viewer (paid license)?


For paid licenses, the activation is permanent.

You will only need to reactivate when you transfer your RadiAnt DICOM Viewer license to another computer or when you renew your Update & Support subscription.


How can I transfer the license to another computer?


First, you need to deactivate the license on your "old" computer. After successful deactivation, the license can be activated on a new machine.

Please note, a license can be transferred only once in a 90-day period.


I have purchased N licenses. Can I install RadiAnt DICOM Viewer on more than N computers?


No, you need a separate license for each computer (or terminal) on which RadiAnt DICOM Viewer is installed (or used).





What is deactivation?


Deactivation lets you transfer your RadiAnt DICOM Viewer paid license to another computer.


How often can I deactivate a license?


A single license can be deactivated only once in 90 days.

A license key valid for N licenses can be deactivated N times during a 90-day period.


Can the same computer be deactivated and reactivated many times?


Deactivation is intended for situations in which you no longer plan to use RadiAnt DICOM Viewer on your "old" computer.

It is not designed for transferring the paid license back and forth between two computers that are in active use. As such, the software can only be deactivated on the same computer twice.

When this limit is reached, you will not be able to deactivate the license.


Is it possible to deactivate a license if the computer cannot be accessed anymore? (stolen, broken, etc.)


Please log in to "My Licenses" account with the email address provided when purchasing the license. You will be able to deactivate your old computer there.
