Please ensure that all letters are capitalised. Furthermore, we do not use the letter ‘O’, only the number ‘0’. Make sure that there are no additional spaces before or after the licence key. For example, you can simply copy this key to the clipboard using CTRL+C and then paste it into the ‘Licence key’ field using CTRL+V.
In most cases, it also helps to start our software once by right-clicking and selecting the option ‘Start/run as administrator’.
If this still does not lead to the desired result, please contact our support team. For a quicker solution, please send us the name of the programme, the licence key and a screenshot of your complete input and the error message. Thank you very much!
