Cannot activate Corel Draw software in Parallels

Hello,

I just got me a new macbook air M2 and currently test out the trial version of Parallel (I used bootcamp on my old macbook pro before) I really want to buy it, however I cannot find a solution for my problem.
I purchased Corel Draw X7 Home and STudent (long time ago) and have the license key for it. Installation ran without issues. But when I start Corel it says "Internet connection is required. Please connect to the internet and try again) I do have internet in Parallels. I can browse the web without issues. I also deactivated my firewall on the mac as well as in Parallels, but it still doesnt work. I have not activate windows 11 (I only wanna do it, if I know for sure everything works. Can someone please tell me what the problem is?

in the firewall is does show to allow Corel Draw connections (private and public)
I have no proxies.

 

sorry to clarify: I can start Corel (30 days trial) but when I click on activate, it shows the connection message.
