Hi Larsi,
Thank you for reporting. you would have installed CIS pro version as it will be free for 30 days and then you need to purchase the license to use the pro version. so that the update function will work.
Currently we have CIS/CFW/CAV V12.2.2.8012 as free product, you can check it out in the below link.
Kindly install and check & let us know your feedback.
Thanks
C.O.M.O.D.O RT
