I would like to buy a new add-on module. How long does it take until I can work with it?
In the case of a local dongle, you can activate the new add-on module very quickly using the authorization file.
We provide you this file immediately after your purchase via e-mail or our extranet.
If you use a network dongle, the only thing you need to do is to write the new information in it.
