Please try requesting a new evaluation license from the B&R website [here](https://www.br-automation.com/en-us/service/software-registration/automation-studio-licensing/). Do you still receive this error after activating with a fresh evaluation license key? ---

Hi, I’m not completely sure, but the message sounds a bit like that the reason could be a cyber security topic described in the following Cyber Security Advisory published on the B&R website: [https://www.br-automation.com/fileadmin/SA23P019\_Automation\_Studio\_Upgrade\_Service\_uses\_insufficient\_encryption.pdf-1b3b181c.pdf](https://www.br-automation.com/fileadmin/SA23P019_Automation_Studio_Upgrade_Service_uses_insufficient_encryption.pdf-1b3b181c.pdf) In that case I think you have to involve your local B&R sales or support contact to get more information how to proceed.

Did you already read this? > [@License code](https://community.br-automation.com/t/license-code/2473/3): > > This will be related to the recent Cyber Security Notice.
