When the manual license activation fails, it means that your license is either invalid (tampered) or it was activated previously.
The license cannot be activated if any detail of it has been changed. For example, if the quantity of runtime seats has been changed from 5 to 6 respectively, you will not activate the license.
In case you already activated your license, contact Querix support firstname.lastname@example.org
If the automatic license activation fails, contact Querix support email@example.com
You can activate your license manually.
