When trying to activate the application with your product key, you may get the following error:


Key already in use


This means the product key is currently activated, and it will not allow you to activate it (again) until the product key is deactivated.


If you are trying to install the product on a new computer, please be aware that your product key is a single-user license, and as per the End User License Agreement (EULA) it can only be installed on a single computer. You will need to deactivate the product key from the initial computer in order to be able to download, install and activate it on another computer.

To deactivate the product key from the current computer:

- Start the IATA Reader

- Locate the publication (enable "View only available" at the top)

- Click on the cogwheel icon

- Go to the Activation tab

- Click on "Deactivate online"

Once this is done, you should be able to reactivate the product on another computer.

You can also consult the following article if you need further assistance with the deactivation process:
