Cannot deactivate my license

Hello team,

I swicthed my license from my PC to my laptop to work remotely. Now that I'm back to my office I need to switch it back. However, I cannot deactivate my license on my laptop, neither with the activation wizard nor offline. 

1. How come I never could deactivate my license offline? Is there a special trick to do it? Or a special reason I cannot?

2. Can you please deactivate my license or tell me how to do it?

Thanks a lot!

Best regards,
