Deactivate C12 license

How do I deactivate the C12 license for the old PC? I have already asked Yamaha(Japan) but don’t have any reply around 3 days… Does anyone know about this?

I think you should be able to deactivate it from the activation manager

Yes, I totally was forgetting to have the Activation Manager application. Now I could deactivate the license on the old PC.
Thank you!
