I have some problem with activation solidworks on my computer. 

When I sign in for the first time, when I try to activate my license, I receive the message "Transaction activation failed: Serial number is not associated with SOLIDWORKS 2022. Contact your reseller. (3/0)" and activation does not occur.

My courses last 18 weeks until mid-March 2023.

What do I need to do?
